Unable To Remotely Connect To SQL Exp
Aug 11, 2007
I have both the develper and sql express installed on my laptop computer. I also have Sql Express installed on my desktop computer( Did have develper installed but removed thinking the problem was in the install). I can connect via Management console from my Desktop to laptop with out any problems. I see databases etc. I can not connect from my laptop to desktop. I get a login error. From what I can tell, the servers are configed the same on both machines. I checked Firewall settings on both machines, even turned them both off with no results. Every time I try to connect from laptop I get Log in error, and I get "Failure Audit" eror under component services.

I have read all of the posts regarding this subject as well as 3"Dummies" guides and I keep having the same problems. I have a verysimple multi-user application that has to hit a database. Wecuerrently have this system deployed and it is working fine on adomain based network. We are scaling back and the network we will beusing is now a workgroup not a domain.It should be simple. I have XP boxes (clients) trying to hit the SQLServer Express database on a Windows Server 2003 machine. It is aclosed network so security is not an issue. I am trying to make thisthing wide open. All I want is for the user to be logged in on hisclient machine, run the application, and access/update the databasewithout having to re-authenticate to the SQL server. I want windowsto handle all of the authentication between the XP machines and theServer 2003 machine.Any suggestions would be greatly appreciated.

Problem: I upgraded a SQL Server Express instance to SQL Server Enterprise, but I'm unable to connect to the SQL server from any remote machine. Only local connections work -- and I've verified that Remote Connections are allowed in the SQL Surface Confg. utility.
Scenario: Server1 has an SQL Enterprise edition installed as a default installation. SharePoint Server 2007 was installed later, and during that install a SQL Express edition instance was installed which is part of the standard SharePoint install. That Express instance contains all the SharePoint content databases.
So Server1 has SQL instances:
Server1 <default install running Enterprise>
Server1OFFICESERVER <previously running SQL Express, now upgraded to Enterprise>
After upgrading Server1OFFICESERVER to Enterprise, everything seemed to work fine (i.e. SharePoint works fine). However when I try to connect remotely to Server1OFFICESERVER I can't. I've verified through the SQL Surface configuration tool that remote connections are allowed. I've rebooted the server as well. I've tried connecting remotely using various PCs and various applications (e.g. SQL Server Mgmt Studio, Visual Studio, etc.).
Any other ideas to try?

Hey everyone. I've been using .NET and SQL server for almost 2 years. I know most of the ins-and-outs, but we hit a bug that requires us to use remote debugging to track down. Like most people, remote debugging does not work out-of-box, but, I've actually tried most of the tips and I still cannot get it to work. Here is a summary of my problem:
------------------------------
Trying to remote debug a SQL Server 2005 database on a workgroup. I am not using CLR, just plain T-SQL.
In Visual Studio, I use the Server Explorer with a data-connection pointed to my remote server and it uses Windows Authentication. It correctly enumerates the available databases. "Step into Procedure" shows the "Run Stored Procedure" dialog with the various input/output parameters. Continuing, I get a dialog that says
"T-SQL execution ended without debugging. You may not have sufficient permissions to debug."
SQL Server is run under Windows Server 2003's window account: 'sqlusr'
Created user on local workstation called: 'sqlusr'
The 'sqlusr' on remote server and local workstation have same password, and are in the Administrator groups
'SERVERNAMEsqlusr' is in SQL Server's bulkadmin, dbcreator, diskadmin, processadmin, securityadmin, serveradmin, setupadmin, and sysadmin roles
Simply running Visual Studio 2005 Professional as my local user does not allow me to authenticate with SQL Server. Running: 'runas /userqlusr "devenv.exe"' will let me authenticate. So - user authentication is apparently working.
I imagine that 'Remote Debugging Components' are installed, since msvsmon.exe is available on the server.
RPC and RPC Locator are running on remote server and local machine
There are no firewalls on the local workstation or remote server (Windows firewall is totally disabled, no 3rd parties..)
Debugging a local SQLEXPRESS database on my workstation works.
'SERVERNAMEsqlusr' has full control over the debugging folder: 'C:Program FilesCommon FilesMicrosoft SharedSQL Debugging'
I haven't seen any errors in the remote server's 'Event Viewer/Application' list
The Stored Proc name I am executing does not contain any single or double quotation marks
SQL Server and Windows Server both share the same name 'SERVERNAME'
Edited DCOM Access Limits and Launch Limits in both the workstation and local server. Allowed 'Remote Access' for Everyone
Any help? I'm out of ideas. Thanks in advance!

If I have SQL 2005 Standard installed on a server and I log on locally to that server. Can I connect to other machines through Management Studio-->Object Explorer that have SQLCE installed and manage the CE DB?
I think you can only connect to either local .sdf files or ones located on a device attached by USB to the local machine, but I have had some difficulty finding a definitive statement on that.
Thanks

Hi
I just installed MSDE over my Windows 2003 box and facing an small problem.
I installed it with SQL security mode and also set a password for user "sa".
Everything looks just fine using "osql" as it uses local address.
But I can't connect to my server from another computer using VS.NET Server Explorer.
It seems as MSDE is set to reject connections from outside by default.
My question is how to enable it so I can connect using my "sa" account.
Appreciate your help in advance.

I just reinstalled SQL Server and after reattaching my databases, I can't connect remotely. If I use "localhost" in my connection string it works fine, but I can't register my remote Enterprise Manager this way.

Hi everyone,
I'm trying to connect to my instance of SQL server 2000 remotely. I know how to do this with SQL server 2005. but since i do not have SQL server 2000 installed on my local machine.. (xp box) I would love to know how i can connect to my remote server?
Is this at all possible without SQL Server 2000 installed ? i have tried to download the personal edition / developer but I couldnt find it
If anyone knows where i can find the developer edition or if there is a trick to get SQL server 2005 to work with my SQL 2000 server it would be greatly appreciated.
thanks

Dear all,
I appologise that incarnations of this topic have been posted several times on this forum, however I cannot find a scenario that is the same as my own so I've resorted to starting a new thread.
I can successfully create and connect remotely to an HTTP EndPoint on my Windows 2003 machine using Integrated security, the administrator username and password via my static IP address.
I have read that Windows XP SP2 supports HTTP EndPoints, and it would be much more convenient for me to be able to create EndPoints in XP, and connect remotely.
I have created the endpoint like so...
CREATE ENDPOINT sql_tvr10
STATE = STARTED
AS HTTP(
PATH = '/sql/tvr10', AUTHENTICATION = (INTEGRATED),
PORTS = (CLEAR))
FOR SOAP (
WEBMETHOD 'StoredProcedure1'
(name='master.dbo.StoredProcedure1'),
WSDL = DEFAULT,
BATCHES = ENABLED,
DATABASE = 'master',
NAMESPACE = 'http://194.106.11.11/' )
In visual studio I can retrive a list of services running at http://localhost/sql/tvr10?WSDL absolutely fine. However, in Visual Studio on the remote machine, I cannot connect to http://194.106.11.11/sql/tvr10?WSDL - it prompts me for a username and password, however I cannot select the username - it is set to "Athlon64Guest" (Athlon64 is my server computer name). I have no passwords on any of my windows accounts (except administrator), and I have no database passwords set.
Could someone please tell me how I should go about accessing the HTTP EndPoint?
Just so it is clear, I am running a small LAN with no domain, just a workgroup. I need the client application to be able to connect via http regardless of which network it is on. I am using VS2005 and SQL Server 2005 Dev Ed.
Many thanks in advance,
Simon

I hope helps some folks. I hope the links come through okay.
Keywords: Help, Network, KB910437, SQL Express, Network, TCP/IP, User,
SQL Server Express Networking
After a long period of trial and error I finally figured out how to connect to SQL Server Express 2005 using SQL Authentication across an XP network. It required several rather involved several steps to do this. I wrote this document just in case I forgot what I did so that I could repair or re-create my network login(s).
I will try to summarize the steps and include some HELP links to the web pages or my local €œSQL Books On Line€? pages that pointed me in the correct directions. The final piece to my puzzle was found here on the MSDN forums. Some links are better than others, while others may appear not to apply, so always check for links at the bottom of pages. Some were the best I could find after the fact, and not my original pages. Others were actually better, and may seem to be redundant. It€™s a work in progress.
I left out many routine or obvious steps like telling you when to click OK. If you need to be told when, you have no business even considering trying this. Good Luck!
PREREQUISITES:
1. You must have an instance of SQL Express installed and running.
2. You must have the SQL Browser service running.
3. You must have SQL Management Studio Express, SMSE, installed on your Server and to be able to log in as an administrator using Windows Authentification. Be familiar with Object Explorer under SMSE.
4. You must have SQL Server Surface Area Configuration properly installed.
5. You must have a functioning LAN, such as a Windows Workgroup.
6. You need a second computer on your LAN running SMSE Tools for testing.
7. You need a strong knowledge of how to use Control Panel.
8. You need to have KB910437 properly installed despite what this might say, although a neat diagnostic command is documented to verify your install.
SUMMARY:
You must enable SQL Networking
You must configure SQL TCP/IP for the server instance.
You must configure the server instance to use UDP Port 1433.
You must enable a UDP port in your Windows Firewall for that server instance.
Test the ability to remote log in using Windows Authentification using SMSE.
You must create a Windows User account for SQL.
You must create a SQL User login Auditing for that Windows User account.
You must grant Permissions to do things for that SQL login.
Now you can try to Log In across a network.
DETAILS:
SQL Networking must be setup by using the SQL Configuration Manager, SCM.
The default installation leaves networking disabled.
Select and use the TCP/IP protocol.
Re-Start the SQL Server service.
Using the SQL Server Surface Area Configuration Manager you must enable TCP/IP.
Select €œServices and Connections€?.
Choose your server instance and then select €œRemote Connections€?.
Choose €œLocal and Remote€?, then €œUsing TCP/IP Only€?.
Re-Start the SQL Server service.
The server needs a means to talk to the outside world. Use SCM.
Setup your IP address by right clicking on the TCP/IP protocol
Choose €œProperties€?.
On the €œProtocol€? tab leave the default settings, (Yes, 30000, Yes, No).
Select the €œIP Address€? tab.
Configure €œIP1€?, (Yes, Yes, enter your IP address, 0, blank).
Configure €œIP All. Leave the default alone.
Enter €œ1433€? on the second line.
Re-Start the SQL Server service.
The server needs to unlock the door to the outside world.
Open Control Panel and select Windows Firewall.
Click the €œExceptions€? tab and click on €œAdd Port€¦€?.
For €œName€?, enter the name of the server instance.
For €œPort Number€?, the same port as Step 3, 1433.
Test to see if Windows log in works before enabling SQL Authentification.
Using the SMSE, select the €œConnect€? icon in Object Explorer.
Accept all defaults and see if it works.
The server needs Windows user accounts setup.
Set up a generic user account for SQL remote users.
I suggest setting up an account for administrators to use.
I suggest setting up an account for general users to use.
SQL needs to add Windows users to SQL Logins.
Convert a windows user login to a SQL login manually or automatically.
The user needs to be assigned tasks that he is permitted to perform.
Grant the user limited access, or just enough.
Assign generic logins to groups, and then assign permissions to the groups.
Use the pre-defined groups. By assigning users to groups.
Test to see if SQL Authentification works locally, then remotely.
Using the SMSE, select the €œConnect€? icon in Object Explorer.

Hello,
I'm using a Windows XP Home laptop to connect to a network of one of my customers. The administrator of the customer has given me a username and password for a VPN connection. I've got the VPN connection working and I can ping the SQL Express server.
This server is using Windows Authentication. For the users of my VB application we have added a group to the Active Directory and added this group as a user to the SQL Express Server. This works and the users can access the database from within the application. The SQL Express Server allows remote connections and the browser service is also running.
I would like to use the SQL management Studio Express on my laptop to access the remote SQL Express server and manage the database files. To do this I first connect to the remote LAN using VPN and add the address of the SQL EXpress server in the field 'Server name' of the 'Connect to server' screen. The authentication field is set to Windows Authentication. However the username is greyed out and states the login for the SQL Express server on my laptop: laptopusername. How can I correct this?
I don't know whether the username of the VPN connection is in the Active Directory. Should this be the case and should this user also be added to the login/user of the SQL Express server? And how do I get the Management Studio to connect to the remote server? Could XP Home be the bottleneck as it cannot logon to a domain?
Anyone any ideas?

Hi,
I am trying to remotely connect to a SQL 2005 Instance on a cluster. I see the following error:
No retry on exception System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I have enabled TCP/IP , Named Pipes on the node. I have turned off IPSec on the clients as well. I am using the following connection string : "Integrated Security=SSPI;server=servernameinstancename;Pooling=false;database=TrialDB"
Is there something I am missing?
Any pointers will be appreiciated.
thanks.

I've just bought a Virtual Private Server Account because I want to host a number of different ASP.NET sites, each backed by their own SQL database. I've downloaded SQLEXPRE.EXE and SQLServer2005_SSMEE-x64.msi to the server and installed the database engine and Management Studio Express on the VPS.
My problem is that I cannot access the SQLEXPRESS on my server from my local machine. The Management Studio Express cannot get logged in. I've used "Surface Area Configuration Manager" to allow "Local and remote connections" using TCP/IP only. I've used SQL Server Configuration Manager" to enable the TCP/IP protocol. After making these changes I've stopped and started the SQL server - and even rebooted the machine. I've created a login "Remote User" for this access. I've added sqlservr.exe as an exception to the firewall.
What else do I need to do? Is there a simpleton's guide to completing this task?

Hi all,
WSUS is installed on my windows 2003 server. During the install, parameter DISABLENETWORKPROTOCOLS was not specified, and so no remote connection was possible.
I used SVRNETCN.exe to enable TCP/IP remote connection on port 1433. However it seems not to work.
FROM THE SERVER :
osql -E -S MYSERVERWSUS works fine but
osql -E -S 127.0.0.1WSUS doesn't work, i get the famous error
[DBNETLIB]Serveur SQL spécifié non trouvé.
[DBNETLIB]ConnectionOpen (Connect()).
If i user "osql -L" command, my instance doesn't appear in the list
FROM A CLIENT COMPUTER
osql -E -S MYSERVERWSUS and
osql -E -S MY_SERVER_IPWSUS don't work, i get the same error
I've tried tried to understand for hours, and i'm lost. I thought there may be a problem between SQL and 2003, and read SQL sp3a was required. I ran
select @@version from osql and got result
Microsoft SQL Server 2000 - 8.00.881 (Intel X86)
8.00.881 is not referenced in ms support as a patched version number !!!!!
Can anyone help me please ?

Hi all,
I have to deal with a private network of laptops which are all equiped with preinstalled "Windows XP home"
I've installed SQLExpress on one of these, but I cannot connect on it from the rest of the laptops. (I've successfuly done this with "Windows XP profesional" though, and local connections work fine as well).
I've already setup the SQLExpress to accept conections throuigh TCP/IP but I can not think of something else. (Security comes to mind, but I do not know how to resolve it on "Windows XP Home").
Thank you

All,
My ISP does not allow me to remotely connect to my hosted SQL Server DB--how can I use SQLDataSource and other data bound controls in development?
Here are my specs:
IDE: Visual Web Developer Express 2005
Database: MS SQL Server
ASP Version: ASP.NET 2.0
The SQL Server is hosted centrally at the ISP; basically I have been given the connection string parameters.
My question is this:
Do I use two web.config files (one for when I develop locally and one for when I deploy remotely)? If so, how? Will the SQLDataSource control find the connection string defined in web.config on the remote server? I don't want to have to write all of the database code and it would be a big loss of one of the major benefits of using ASP.NET 2.0 if I do.
Any help will be greatly appreciated,
Leslie

Hi all, I'm having a little trouble connecting to a SQLExpress instance on a remote domain using SQL Server Management Studio Express.I've read that by default the program is set up locally only, so have edited the Surface Area Configuration. It only gives me the option to edit 'Services and Connections' on the localhost, but have edited the Remote Connections to use TCP/IP and Named Pipes. In the Management Studio, I enter the server name, and login credentials. On the Connection Properties tab I changed the network protocol to TCP/IP though everytime I attempt to connect I get the following error message: Any help would be greatly appreciated. Rich

Someone please help me before I loose all of my hair :mad: !!!
I have two machines, a Windows Server 2003 machine running an SQL Server Standard Edition database instance and client tools (Enterprize Manager etc.), and a workstation PC running Windows XP SP2 which has just the SQL Server client tools (not an actual DB instance).
I'm trying to use the Enterprize Manager client tool on my WinXP machine to remotely connect to the server instance on the server PC (via 'New SQL Server Registration' option). Everytime I do this I get the following error message:
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server Connection.
Now I've tried using different usernames and passwords. I have login details for my SQL Server set to use Windows Login rather then SQL Server login, so I tried remotely connecting with the username and password for the server PC, tried 'sa' with server password, even tried setting up a new user on the server and logging in from the client with that, no luck. I've opened up correct ports 1433 on both PCs, even disabled the windows firewalls algother. Both server and client have SP3a installed, WinServer2003 has SP1 and XP SP2.
So I'm at a loss to how to remotely connect to my SQL Server. FYI I know the server itself is working fine because I can connect to it using Enterprize Manager/Query Analyser on the local machine. Any ideas? Many thanks for your help!

Hello everybody
I wrote a vb.net win app that uses a mssql 2005 express DB.
On my localcomputer everything worked without a problem.
Now I wish to deploy my app on a remote computer (that has mssql 2005 express installed), so. I added an app setup project to my project using the vs2005 setup tool, installed the app on the remote computer, and copied the mdf file to the remote computer.
I'm able to see the DB through the remote computer mssql manager, But when I try to start the app on the remote computer I get this error massage :
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. error: 0 - No process is on the other end of the pipe.)
my connectionstring (in the config file) looks like that :
<connectionStrings> <add name="Info_Manager.My.MySettings.MaxinetConnectionString" connectionString="Data Source=DOTAN-XPSQLEXPRESS;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> <add name="Info_Manager.My.MySettings.MaxinetConnectionString1" connectionString="Data Source=DOTAN-XPSQLEXPRESS;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataMaxinet.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" /> </connectionStrings>
by the way changing the user instance attribute to "false" didn't help.
Does anybody know how to fix this problem.

Everything has been working fine our SQL Server (lets call it Server A) (v2000 under NT 4), however sometime over the weekend it is unable to connect to one of our other SQL Servers (Server B).
In the Event Viewer I found this error:
SuperSocket info: Failed to get Exclusive port use(MSAFD Tcpip (TCP/IP)): Error 10013.
Everything on this server appears to be working fine, as in everything can connect to Sever A that needs to, but Server B can't connect to A, nor is it working the other way.
Also, Server A SQL Services run on port 2006, and B is on the standard 1433. Everything has been working with this up until today?
Any ideas?
Thanks!

Let me start by saying that, yes we know v6.5 is no longer supported byMicrosoft and that moving to SQL2000 might resolve our problem.Actually the migration to SQL2000 is 1 to 2 months out and in the QAphase now. Unfortunately we need to resolve the current 6.5 issue nowas it heavily impacts a major revenue stream for the company with everyoutage we encounter.The Problem:At least once every 24 hours the SQL Server begins disallowing new userconnections. When this happens the 2 CPUs begin to thrash. About 5minutes later the error log begins to print out the following errormessage: "Unable to connect. The maximum number of '500' configured userconnections are already connected. System Administrator can configure toa higher value with sp_configure." No new connections can be made to theserver; however, the existing connections continue to function normally.We never see anywhere near 500 user connections in the system (it tendsto average around 350 connections). If we begin to disconnect users theserver continues reporting that the maximum number of users isconnected. Eventually running queries thru an open connection will hangand we have to resort to a hard reboot of the server as neither SQLServer will not shutdown nor will the operating system.The Server:Compaq Proliant DL380 with dual 863 MHz. processors (x86 Family 6 Model8 Stepping 3 GenuineIntel), 917,020 KB of physical memory, MicrosoftWindows 2000 Server (Version 5.0.2195 Service Pack 4 Build 2195), TotalVirtual Memory 3,138,688 KB, Page File Space 2,221,668 KBSQL Server:Microsoft SQL Server 6.50 - 6.50.479 (Intel X86).

I am unable to connect SQL Server Management Studio to any of the databases on my computer. At this stage I am simply starting the Management Studio and asking it to connect to a database I made a few months ago before this connection trouble arose. I'm specifying the server name "BENCHLAP" which is the name of My Computer, using Windows Authentication.
The error I get is:
An
error has occurred while establishing a connection to the server. When
connecting to SQL Server 2005, this failure may be caused by the fact
that under the default settings SQL Server does not allow remote
connections. (provider: Named Pipes Provider, error: 40 - Could not
open a connection to SQL Server)
The client is local. At least, it is if I understand correctly - the instance of SQL Server is installed on the same machine as the instance of IIS that I intend to use to test my web applications after we have resolved this issue, and the same machine as the one I shall use to view the application on.
I can ping the server if i type "ping -a BENCHLAP". It is successful
I think it also connects via telnet ok as well, by typing "telnet BENCHLAP 135"
All client protocols are enabled, as are the server protocols. Don't know if this is a security risk but I did it to try and solve the problem, to no avail. There are no aliases, according to the Configuration Manager.
The server itself is SQL Server Express 2005, runnning on Windows XP Professional. My anti virus software is AVG.
I'm afraid I don't know anything more, and have been researching this error for quite some time now.
Is anybody able to help me please?

Cannot someone please help me with following problem. I am trying to create a program to update a sql datbase from.NET 2003. I am doing this by using SQL Server Express 5. The problem is, is that when I run the program and click the button to view the table in SQL Express 5 I keep getting an 'System.NullReferenceException' and the table is not shown. When I look at the debug details it says that 'object reference not set to an instance of an object'.
Am not sure where am goin wrong as the connection is opened to the local server in SQL Express and I have created a connection object and initialised it to the address fo the datatable in SQL.
Please find below the code I am working on which shows the connection string in question and the table being called in button 6 which causes the exception.
Any help would be greatly appreciated....thanks
