Error Connecting To An Instance Of SQL 05 Remotely
Oct 11, 2007
I have SQL 05 and SQL 200o on same server . SQL 05 version is a named inatnce. But when i try to connect it from my computer first it doest show the name instance in the list and when i manulay write its name i got this error.
"A connection was successfully established with the server, but then an error occurred during the pre-login handshake. 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: 0 - No process is on the other end of the pipe.) (.Net SqlClient Data Provider)"
I went to check that remote connectiona nd SQL browsing is on or not but both were on . any ideas why this is happening and why the name is not coming in list of Server.
Thanks

I've been trying to configure remote connections to my sql server express to no avail.
First here are some constants to clear some things up:
- OS: Windows XP Pro
- SQL Express version: April CTP release
- Windows Firewall: disabled (to avoid any problems there)
- Network type: two computers connected a router.
- Router firewall: Enabled (I may be wrong but the router firewall only blocks external traffic, so I left it on.)
First, I configured my SQL server to allow remote connections in the SQL Surface Area Configuration. (Set it to both TCP/IP and named pipes)
Second, I enabled and configured sql server browser.
Third, I enabled TCP/IP and named pipes in the 'Protocols for SQL Express' option of the SQL Server Configuration Manager.
According to http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
I have done everything I need to (including edit the registry to enable the SQL Server Browser service) and the error I continue to 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)"
So I tinkered and had no success in messing with anything that would fix it. Although, ***when I browsed for network servers on different machine, the server instance DID show up in the list***. So I find it odd that it can find the instance when browsing, but fails to 'find' it when making a connection.
So I didn't stop there, I decided to try the non-sql server browser method of remotely connecting: specifying the IP.
I went back to the blog of instructions referenced above and re-did the steps, this time specifying a TCP Port for the server instance and then after specifying the port on the remote computer connection string, and attempting to connect, I get this error:
"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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) (Microsoft SQL Server, Error: 10060)"
I've done all I know how, read all the possible blogs I can, and nothing's come up. If anyone can shed some light on me, I'd pay you 1 billion pretend dollars. Any help would be appreciated. Thank you!

I do hope someone can help
I have a windows server with SQL Express, I have followed the link here and still no luck
http://blogs.msdn.com/sql_protocols/archive/2007/05/13/sql-network-interfaces-error-26-error-locating-server-instance-specified.aspx
I have checked and checked again a thousand times
I can remote desktop and connect through SQL Management Express, but when I try this on my local machine I get the error 26
My knowledge is very limited and could do with some expert help
PS EDIT
I read somewhere that in TCP/IP properties all IP's should be set to 1433, is this correct
at the moment, apart from ALL IP which is set to 1433, IP1-9 are set to Dynamic Port =0, should I be setting all these to 1433
??

I am attempting something that I have done many times before; however, in this instance it continues to fail.
I am trying to connect Management Studio to an instance of SQL Server 2005 Express over a VPN. The Management Studio connect dialog always fails with Error 26.
I have:
Enabled the instance for remote connections €“ both TCP/IP and Named Pipes
Ensured that the instance is enabled for TCP/IP on the VPN address (10.2.1.1) and on port 1433
Ensured that the instance is running
Ensured that SQL Browser is running
Ensured that ports 1433 (TCP) and 1434 (UDP) are open on the firewall for inbound traffic
Rebooted the server following this configuration to ensure that the instance services are refreshed
Tried to connect from three separate clients (albeit on the same remote network)
Disabled the firewall to ensure no further complications (as a last resort)
I have this exact same setup functioning on a separate server.
There is an additional backstory to this problem; however, I will not complicate the scenario with it now. If you feel you can help then I can elaborate further on the server€™s history.
Thanks
James

Greetings,
I have a VB 2003 .NET application that I wrote for a customer that connects to a named instance of SQL 2000. Until recently it has been working fine. Lately the program either pops a timeout failure within a few seconds or a general network error. I've increased the connection timeout settings to 90 seconds but the error still pops within a few seconds. I'm thinking something has changed in the environment that prevents a clean connection to the named instance of SQL server.
How should this issue be troubleshoot to determine the problem and what areas need to be looked at?
Thanks

I have a named instance of MSDE running on my windows 2k3 web server. I can connect just fine using ODBC to that DB whailst I am on the server.
I would like to be able to create an ODBC connection from my local machine (running Windows XP pro) to the MSDE database on my server but I can't get it going.
I have heard that I need to edit the registry but a Google search warns that this could be a vulnerability...
How do I do it without compromising the security of my web server?
TIA

I'm new to MSSQL. At my work place, I'm using MSSQL and using SQL Query Analyzer to run queries and view all my database tables and structures.
Now, I can work remotely at home for the time being. So, how do I get SQL Query Analyzer and be able to connect remotely to my database at work?
I've downloaded SQL Server 2005 Express and it comes with SQL Server Management Studio, which looks similar to SQL Query Analyzer. The problem is though, how would I remotely connect to my database server at work? Is it possible to do this using SQL Server 2005 express?
One thing I was advised to do was configure the TCP/IP Port number from 1433 to 1435. However, I do not see an option to configure that nor do not know how to connect remotely (I do have the IP, User, and Pass).

Hi
I hope this is the right place for this question.
I'm using SQL 2005 Express on my local machine, I can connect and do all I need to.
But when I transfered my database to my remote server I cannot connect (I changed the connection string to suit).
<add name="ClubSiteDB" connectionString="Data Source=xx.xxx.xx.xx,1786;Network Library=DBMSSOCN;Initial Catalog=xxx;User ID=xxx;Password=xxx;" providerName="System.Data.SqlClient"/>
I have checked the connection string passsword etc, and all are correct.
I have tried SQL Server Management Studio, aspnet_regsql.exe etc and all give the following error:
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: TCP Provider, error: 0 - No such host is known.)or
System.Web.HttpException: Unable to connect to SQL Server database. ---> 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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
I have used the surface config to enable TCP/IP and named pipes.
Any Ideas?
Thanks

Hi,
I am using osql to connect to my remote MSSQL server. I am able to get a prompt for password and telnet to 1433 just fine, so I conclude this is not related to firewall. When I try to connect I get:
C:Program FilesMicrosoft SQL Server80ToolsBinn>osql -S xx.xx.xx.xx -U test
Password:
[DBNETLIB]SQL Server does not exist or access denied.
[DBNETLIB]ConnectionOpen (Connect()).
When I try to connect from 'localhost':
C:Program FilesMicrosoft SQL Server80Toolsinn>osql -U test
Password:
1>
--
This is Microsoft SQL Server 2005 - 9.00.1399.06 and both local and remote connections are allowed. Logs don't show up anything.
Thank you.

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.

Hi,
I have 2 machines using SQL Server 2005 developer edition. I am able to connect to each of them locally without any problem. But when I try using one SQL Server as server and another machine's SQL Server as client, I am not able to connect. I get the following error:
TITLE: Connect to Server
------------------------------
Cannot connect to ServerName.
------------------------------
ADDITIONAL INFORMATION:
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. 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: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233).
I have checked for "Allow Remote Connections" property turned on for TCP/IP.
I am using SQL Server Authetication mode.
I have checked for SQL Server Browser service to be running.
Firewall on the server is also allowing the sql server traffic to pass.
But still not able to connect. What could be the problem connecting the 2 machines.
Any help is appreciated.

New sql2005 install as a named instance and having trouble connecting from remote machines.
I noticed on our other servers that the "Public" server role is listed in permissions (right-click over the sqlmgr connection for the dialog, then permissions).
When I try to add the role to the new server it doesn't save! This is the only setting that's different, can't connect using sqlmgr from other machines to this server so any ideas on other settings to look at appreciated.

Hello,
Only the server administrator user can connect to SSIS from remote workstations. All other users encounter "Access denied". What security settings are necessary to permit regular user access to SSIS? Firewalling is not an issue. SSIS is running and works fully for the server administrator user. All users can manage the Database with SSMS just fine; only SSIS cannot be accessed by regular users.
Server Configuration Notes:
Windows Server 2003
SQL Server 2005 Standard
Workstation Configuraiton Notes:
Windows XP Professional
SSMS (installed from the SS2005 media)
Thank you.

Good Day,
I am creating a SQL Named instance as a testing environment. This instance is on the same physical box as my Development environment, both are SQL 2005 standard edition. From the server in Management Studio, I can load, and interact with both instances. From a remote connection (e.g., my pc) I cannot access the named instance. I am getting the following:
Connect to Server
X Cannot connect to <server><named instance>
Additional Information
An error has occured while establishing a connection to the server. When connecting to SQL Sever 2006, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)(Microsoft SQL Server)
I have checked, and rechecked the server settings for this named instance, and remote connections are set to "allow" I have enabled TCPIP and Named Pipes prototocals, and have ensured that my firewall is allowing the "listenting port" for the named instance, and have even tried turning off my XP firewall during testing.
I am sure that I have probably missed something, and have searched the community but only have been able to find resolutions that I have already tried. Is there more?
Thanks in advance for any help and guidance you can provide.

Hi
I have installed SQL Server 2005 onto a server and then on my client machine I have installed SQL Server 2005 and the Server Management Studio.
When installing it on the server I chose all the defaults so have not setup an sql username or password to connect as I thought I could use Windows.
I go to the Server Management and registered servers, create a new one and enter the ip address of the server and choose Windows Authentication. The following error keeps appearing though and I am not sure what settings/where to check:
Login failed for user ''. The user is not associated with a trusted SQL Server connection. (.Net SqlClient Data Provider)
I have checked and think port 1443 is open on the server, tcpip is enabled but when I choose Windows authentication I cannot enter a username or password as it is greyed out. It has completed the username but no password and these are not the correct ones to connect to the server - I wish to wish the same one I use for RDC.
Or should I try SQL Authentication and if so how would I set this up? Cannot see on the server in SQL Configuration where I could set this?
Hope someone who knows a lot more than me on this can help!
Thanks for your time - this has been driving me mad for days now and everything I print off the internet is not help so any feed back or more useful links to loo up would be great.

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!

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?

I had asked a question last week and I realized that I had phrased it in a misleading way. Within a lab environment at my company, we are experimenting w/ accessing remote SQL data files stored separately on another machine from the SQL server itself (whether it be another client or server).
The experiment is this: You have one client machine accessing a SQL server via Enterprise Manager. The datafiles that you are trying to access are stored on another machine that does not have SQL Server installed. This remote machine only has the datafiles.
Can one map a static path via UNC from the SQL server to the datafiles on the remote machine and then access these datafiles (as long as the user's account has the appropriate permissions to the remote machine)? To my understanding, within SQL server you can only access datafiles that are stored locally on the SQL server itself.
The other thing that I was wondering was if the type of user account had some significance in this situation. More than likely, a local user account would not be able to access the remote machine w/ the datafiles even if the SQL server could map an UNC path and retain it. A domainuser account might be able to do this though.
Any help that you could provide would be appreciated.

Hi,
I have two SQL SERVER Instances on the computer I am trying to connect to via VPN:
1) TEST
2. TEST/INST2
I can connect to the first with no problems.
When I am trying to connect to the second (with the Enterprise Manager/Query Analyzer and even with isql) - I get the following message:
"SQL SERVER does not exists or access denied".
I use the SQL SERVER user and password to connect (as login sa).
How can I connect to the second instance?
Thanks in advance.

When I run “select @@version”, I get SERVERNAMESQLEXPRESS, but I can’t connect to the server with SERVERNAMESQLEXPRESS. This is throwing off one of my script when trying to connect to the server.My script connects to the server using SERVERNAME for default instance or SERVERNAMEINSTANCENAME for named instance.

Hi
I am really struggling with this problem.
I am connecting to several SQL 2000 servers on another LAN from my workstation and I have to go through a firewall.
I got the firewall people to open port 1433 and was then able to connect any server with a default instance using Query Anlyzer and the IP address of the Server.
When I try to connect from my workstation to a server with a named instance I am being blocked by the firewall before it gets to the server.
I went into Client Network Utility on my workstation and removed named pipes which only left Tcpip using port 1433.
Fire wall is now blocking “nbname UDP 137”.
Is there a setting somewhere on my workstation that I can force the traffic to the named instance to use Tcpip through port 1433.
Any Help would be great.

We have installed SQL 2000 SP4 on Windows 2000 Server. We created named instances on the SQL server.
When trying to connect to named instances from a remote sql client which is on windows 2000 and windows 2003, its throwing an error message saying that remote connections are disabled.
But, remote connections are enabled on the SQL server.
After changing the component services settings on windows 2003 where sql client is installed, we are able to connect to named instances.
But, after applying the same settings on another windows 2003 machine, we are unable to connect to the same instances.
We have another machine where we installed SQL 2005 on windows 2003 SP1. When trying to connect to named instances from any remote client, its throwing an error message saying that remote connections are disabled. But, remote connections are enabled in SQL server settings. We tried connecting to the instances by changing the component services settings but still we are facing the same issues.
Can you please help me on above issues?
