Remote Connection Problem With Sql Server Express
Jan 24, 2006
Hi
have sql server express 2005 installed on a laptop running XP sp2 with IIS installed. installed sql express during the visual studio 2005 install
having problems with remote connection errors messages when using aspnet_regsql.exe as well as when trying to view pages with sql db involved. in most tests to fix this i disable my firewall, still getting error messages tho
sqlBrowser is running as is sqlexpress in services both on auto
in the surface area configuration tool, the remote connection is set to local and remote connections is using both tcp/ip and named pipes.
in sql config manager- shared memory, tcp/ip, and named pipes are enabled for both the server and the client, the order on the client is shared memory then tcp/ip then named pipes
inside the server's tcp/ip on the ip tab, IP1 is set to active, enabled, the ip address is 192.168.1.41 which is different from the laptop ip (192.168.1.39), there is no port number for IP1, should there be a port number?? dynamic port is 0
IP2 is set to active, enable with address 127.0.0.1 and also does not have a port number, dynamic port is 0
IPAll is using dynamic port 1232 but also has no port number.
for the client TCP/IP setting the default port is 1433 and it is also enabled.
also downloaded and intalled SSMS-EE and under properties for the sql server >connection, the allow remote connection box is checked. I am using the default instance sqlexpress, there is another instance microsoftbcm (what is that??) and it also has the allow remote connection box checked.
server security is set to windows authentication
keep getting
clues appreciated, take care

Hi all,
I have SQL Server Express and VB 2005 Express installed in a Microsoft Windows XP Pro PC that is a terminal PC in our office Network. My Network Administrator has granted my terminal PC for Administrator Use. I tried to do the ADO.NET 2.0-VB 2005 programming in my terminal PC and I could not get a remote connection in the Window Form Application via Window Authorization. I do not know how to make this kind of remote connection in my Network. Please help and advise.
Thanks in advance,

It has been installed with windows authentication.
I can use sqlcmd -S machinenameinstancename to connect to the server, but when I try to connect from another machine on my lan, I get the error about user not part of trusted sql connection msg 18452 level 14 state 1
I have tried using a windows username and password from my server to access it but that fails also.

Hi ,
After reading the SQLexpress weblog , I tried the solution and its still not working
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
The client computer gives me this:
Run-Time error -2147217843 (80040e4d)
Log-in failed for user "KitGuest"
The connection string in the ADO object in my testing VB6 program is:
my_connection.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;User ID=kit;Initial Catalog=AdelaideMushroom;Data Source=KITSQLEXPRESS"
I am confused with the error massage as my conncection string is set to connect on UserID = Kit
I am not sure what is gone wrong. The same VB6 program runs perfectly on host machine
I am not sure is there anything to do with SQL Config. Manager's SQL server 2005 service's Log-ON setting:
Log On as - Build-in account: Network service
could Anyone who managed to get remote connection work give me some advise?? I am desperate. have read that weblog many times and do not know how to get it work

I have recently installed SQL Server Express on a desktop machine for a program that we use. I am in need of adding additional machines to gain access to the server for the database. Right now, the program is working on the local machine fine. What do I need to do or enable for access on a local LAN? All machines are XP Pro on a workgroup. Also, the software we use has a remote connection manager that requires inputting the server address for the machine. Is it better to use the computer name or IP address, and then what is that format? SQL Instance name is 'uesafh' if that helps. Any other information that I can provide, please let me know.
Thanks!

I am new to VB.Net coming from a VB6 background using the VB.Net Express and have even loaded the SQL Express. The learning curve is not to bad until you get to dealing with connecting to db's. However, in trying to fill a grid with data, manipulate it and then update it has not been any fun either. There does not seem to be enough information out there dealing with these two as of right now.
Anyway, trying to add a datasource connection for a grid has resulted in a real problem even using the connection wizard. I keep getting the same error that the default settings for SQL express does not allow remote connections. However, I thought that I have corrected that. Unfortunately, with VB express I cannot even seem to talk to my SQL 2000 server either because it gives me the same exact error. I am thoroughly frustrated with it and ready to just do it in VB6.
I am open to any thoughts on this. I do not like using bound controls, except in a few situations. I would like to create it unbound if at all possible. If someone could give me some ideas as to what to do and where to go with this I would appreciate the help. I have been doing a lot of reading and a descent understanding what is needed to talk to a SQL db.
Thanks in advance.

Hi,
I have written a database application using .mdf in visual studio 2005 using vb.net (Windows XP sp2)
The app runs fine on the local machine. But I want to access the database from another computer (remote connection)
My Questions:
1. How to host the database file (mydb.mdf) on server machine?
2. How does connection string change on the client side?
Any other idea?

Good day.
I am trying to look at a friends database that they have developed. Not having used SQL Server Express before I am experiencing problems trying to remotely connect to their database.
He connects locally just fine of course.
I get the error message about remote connectionsand the default settings so I have enabled TCP/IP and Named Pipes as well as cleared SQLSERVER Express in my firewall settings. I also stopped and restarted the service, but still get the same error message.
My connection parameters are like:
Server type: Database Engine
Server name: http://sql.exampledatabase.net (should http be here? have tried with and without same error)
Authentication: SQL Server Authentication (windows authentication? If so, how do I change to such?)
Login: http://username (should http be here? have tried with and without same error)
Password: password
TITLE: Connect to Server
------------------------------
Cannot connect to http://sql.exampledatabase.net
ADDITIONAL INFORMATION:
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) (Microsoft SQL Server, Error: 53)
Any help would be much appreciated.

Hi,
This might be obvious - but if so I've missed it so far.
Is it possible to connect remotely to an Express database used in a website which is created in the App_Data folder by VWDEE 2005 and attached by filename?
As far as I can tell these databases don't have a name and aren't mounted until an attempt is made to access them. I certainly can't see any sign of it in SQL Management Studio.
Thanks,
Dale

posted to the forums a few weeks ago, followed the suggestion but the problem has not been squared, the link for my original post is at the bottom of this message.
have tried most of the suggestions in the forums, again see the link for details on steps i have tried, kept poking around and came up with a few more possibilities for the problem,
the error message is the one that says sql server express remote connnections are not enabled by default during the install of sql express,
backed up a little and it seems i can not even connect to the local machine, i ran the sqlcmd -s -e sqlexpress and the login timesouts and says that sql express refused the connection, have shared memory protocal and tcp/ip running also tried it with named pipes,
so that left me wonderin if maybe permission for sql express need to be adjusted, brought up SQL server Studio Mangement Express console and went to the only express instance on the local machine, brought up properties for sqlexpress and went to the permission section and noticed the following:
for the BuiltInadministrator and builtInUser account the only permission that is checked off is the "Conect SQL" which has only the Grant checkbox checked, also the grantor is sa, btw what does the checkbox With Grant do?? this was the same for the both accounts,
for the public account the only permission that is enabled is the View any database,
are there other permission which need to be granted or "with granted", also i assume i should not be using the sa account or should i?
other things going on include include Visual Studio 2005, i am able to get to the database thru Server Explorer, and can bring up the tables and see them, sometimes thos their is a red x on the mdf, but when i click it brings them up.

I have Microsoft SQL express server 2005 setup on one server and I have a website setup on another server, I am trying to get some data from the SQL server on the other one.
I am currently getting 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.) I have done plenty of searching on Google, and already been through the tutorial on changing the setting in ‘SQL Server 2005 Surface Area Configuration’ to allow remote connections
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspxhttp://support.microsoft.com/default.aspx?scid=kb;EN-US;914277
It works perfectly when I call data from my local machine.
Also I don’t know if it is a timeout issue, because I tested in on two other servers I have access to and it worked on one of them.
Any help would be very much appreciated.
Thanks in advance.

I followed the steps outlined in a blog I found to setup SS2005 express for remote connections. Everything appeared to go smooth until I actually tried to logon ;)
I have Sql Server 2005 Express installed on my WinXP PRO machine at home (no domain). I have opened the ports on the firewall, etc.
When I try and login from the SQLCMD command line tool I get a Login Failed error. Here is the connection string that I'm trying to use:
SQLCMD -S **.***.**.*SQLEXPRESS -U Steve -P MyPassword
The error:
Login failed for user 'Steve'.
When I use Management Studio Express on the same machine running Sql Server, it shows the User name: NEVERSTILLSteve
'NEVERSTILL' is the name of my computer.
If I try and use that same username with a remote connection I get the same error.
I have googled for the error and msg code, but nothing fitting my situation is coming up.
Anyone have any ideas for me?

Hello,
2 weeks ago, I installed a SQL Server 2005 Express on one of my computer. I fought to configure the remote access, but finnaly it did work.
Yesterday I had to move my server on another computer and I've never succeeded in configuring the remote access. I don't understand why it is so complicated to install remote access.
I explain you what I did, and if you could say me what i missed, it could be amazing !!
I install SQL Server 2005 Express including the SQL Server Management Studio Express.
I went to the SQL Server surface area configuration and i enable Remote Access (TCP) and turn on the SQL Browser
I enabled Server authentication => SQL Server and Windows Authentication mode.
I created users with all the permission i can give to them.
I restart one million time all the services and nothing...I tried to connect to the database using my local Microsoft SQL Server Management Studio Express, using the Visual studio Sever Explorer and with C# script using this connection string :
sConnectionString = " Server=myIP\SQLEXPRESS; Initial Catalog='myDatabase'; user id = myLogin; password = myPassword";
And I've never succeeded in connecting, I have always the same 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)which means the database is not reached.
Please tell me i've just missed a stupid thing.

Hey all!
I've tried all I know in an effort to get SQL 2005 Express to allow remote connections on my customer's 2K3 server and I'm not having any luck. I've followed MSKB 914277, including adding the exceptions to their Windows firewall...even disabled the firewall altogether (for testing purposes), and I still can't get remote clients to connect. As suggested by various other posts, I used netstat -an to confirm that SQL is listening on port 1433 for the desired IP on the server.....and saw that it is listening. Here's a snippet:
TCP 192.168.0.2:1433 0.0.0.0:0 LISTENING
TCP 192.168.0.2:1433 192.168.0.2:1738 ESTABLISHED
TCP 192.168.0.2:1738 192.168.0.2:1433 ESTABLISHED
TCP 127.0.0.1:1433 0.0.0.0:0 LISTENING
I can connect to the database locally (i.e. on the 2K3 server itself) using just the IP address .... tried with a DSN, UDL, ODBC, and SSMSE...all of which have no problems (as shown by the two, "ESTABLISHED" entries in the netstat results above which were from running SSMSE locally on the server at the time of the netstat). But if a remote computer on the network tries to connect, they cannot connect. Sorry, I don't have a copy of the error message the clients are getting yet.
I asked The customer's IT to confirm that the clients CAN can "see" the server (i.e. that there wasn't some kind of router or firewall blocking their path) and they sent me a copy of the server's pfirewall.log file. Here is an entry from the file that seems to show that client requests ARE getting to the server:
2007-12-17 19:12:13 OPEN-INBOUND TCP 192.168.0.4 192.168.0.2 1213 1433 - - - - - - - - -
2007-12-17 19:12:13 CLOSE TCP 192.168.0.2 192.168.0.4 1433 1213 - - - - - - - - -
I'm starting to get in over my head here (I'm a programmer, not a DBA or Net Admin), but doesn't the above suggest that an incoming request came in from .4 on port 1213 and attempted to connect to .2 on port 1433, but the connection was denied or dropped by the server? If so, why? Is this related to another MS KB I read about connection pooling? I'm way over my head here and could use some help. Did I miss something subtle during configuration of SQL Express?
Thanks in advance.

Hi all,
In my office computer network system (LAN), my Windows XP Pro PC has SQL Server Express and VB 2005 Express installed and I was granted to have the Administrator priviledge to access SQL Server Express. I tried to create a SQLCLR project in my terminal PC.
1) I tried to set up a remote connection to SQL Server Express in the following way: SQL Server EXpress => SQL Server Surface Area Configuration. In the Surface Area Configuration for Service and Connection - local, I clicked on Remote Connection of Database Engine, SQLEXPRESS and I had a "dot" on "Local and remote connections" and "Using TCP/IP only". Then I clicked on "Apply" and "OK" buttons. Then I went to restart my database engine in SQL Server Management. When I went to check SQL Server 2005 Surface Area Configuration, I saw the arrow is pointing to "Service", not to "Remote Connections"!!!??? Is it right/normal? Please comment on this matter and tell me how I can have "Remote Connecton" on after I selected it.
2) After I restarted the database engine (I guess!!), I executed the following project code (copied from a book) in my VB 2005 Express:

Hi all,Just wondering if SQL 2005 express edition can be connected remotely. I've set up SQL 2005 Express on a separate machine and am having trouble connecting to it from VWD when creating the websites. Currently I've set up ASP.NET 2.0 Framework on the remote machine with IIS6 using Windows Server 2003 Web Edition. And I am directly editing the website remotely on the server machine from my PC. Could someone please help me in setting up a remote connection from VWD to the SQL Server?I've enabled TCP/IP setting in the SQL Configuration Manager but still getting errors. Could this be an issue with Express Edition? Because if it is I also have a copy of SQL Server 2005 to install. Any direction to resolve in this issue would be greatly appreciated.PS. I'm new to this so pls bear with me. Thanks.

Hi
I have two machines, the one has Windows 2003 server and the other has Windows Xp Pro on.
The 2003 one has SQL Standard Edition 2000 on where as the XP Pro has MSDE 2000.
I'm trying to run a windows based app from the 2003 server and it connects to a database on the XP Pro PC.
When running the application i keep getting the following exception:
"A Transport-Level error has occured when sending the request to the server (Provider: Named Pipes Provider, error: 0 - The specified network name is no longer available)
After using Preformance monitor on the XP machine it seems that when the app starts and the user logins in it make a SQL connection but then the connection is lost then the exception pops up. then i click continue and try it again then it works, then a couple of secs when using the system it pops up again. The Performance Monitor Test shows that the SQL connection keep being lost. The network is fine. its has something to do with SQL and Named Pipes and stuff.
When running the app on the Xp machine and the Connection is made to the 2003 machine there is no problem.
There are other connection made to the Windows XP Machine but i doubt that it affects the app.
The Windows firewall is off as well.
Please can anyone help.

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

Hi,
I've worked with SQL Server plenty but never in this specific manner. Hoping someone can shed some light.I have a webform on web server A that needs to talk to a SQL server database that web server B accesses via its web application. I do not haveany privelidged access to server B or the sql server it uses (no FTP to webserver, no remote access via Enterprise Manager to the SQL server). The Admin of Server B told me that I can use a DSN connection to talk to the SQL server database that the web app on server B uses. He emailed me the names of the SQL database tables AND a copy of the web.config from server B which shows the DSN implemented like this:<appSettings> <add key="dsn" value="data source=sql3.domainname.net;database=dbname;User Id=dbuserid;password=dbpw;" /> <add key="default_language" value="en" /> <add key="error_email_to" value="someone@domainname.com" /> <add key="baseHref" value="http://www.mysite.com/" /> <add key="website_name" value="$$$$$$$$$$$$$$$$$" /></appSettings>
I was planning to run my webforms on Server A where I do have FTP, Control Panel, etc.So, I wrote this code into my VB.NET codebehind file.
Dim oODBCConnection As OdbcConnectionDim sConnString As String = _"Driver={SQL Server};" & _"Server=sql3.domainname.net;" & _"Database=dbname;" & _"Uid=dbuserid;" & _"Pwd=dbpw"oODBCConnection = New Odbc.OdbcConnection(sConnString)oODBCConnection.Open()... commands to access data and load something into a control on a webformoODBCConnection.Close()
When I attempt to run the webform in my browser from Server A. I'm getting this error:ERROR [08001] [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. ERROR [01000] [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).The error is EXACTLY the same whether I place the appSettings section in server A's web.config or leave them out.I have obvious questions about the error like...Might sql3.domainname.net simply be refusing communication requests that don't come from the Server B domain?Might the sql3.domainname.net be setup so that I need to use another protocol (not tcp/ip)?Might my code need to be changed to support this type of connection (i.e. I didn't code it right)?I spent some time reading http://support.microsoft.com/kb/328306/en-us but I'm at a loss as to what the best course is to take for debugging this.Thanks in advance for any insight you can offer.

I would appreciate any help anyone can offer
I am developing a web application that needs to access SQL Server. I have implemented forms authentication. My Sql server is on another machine and I am unable to connect because ASPNET is a local account. Is there a way around this, I really need to keep forms authentication and I am forbidden to place Sql Server on the same machine

Hi,
Just want to know what I need to check to make sure the remote connection is configure properly other than "Enable the remote connection" for the server? what ports that need to open up if firewall is running on the Server Machine?
I tested with a remote user, it seems the application just hung there and wait.. wait.. it seems something block the connection.
No error message, If I ping from the remote PC to the server, the response time is in acceptable range.
Thanks!

hi
I am developing a web application using C# and SQL Server 2000. It works fine when the Application and DB are in same machine. Now I want to connect to the DB located in another machine in the same network.
I used the connection string as follows.
"Data Source=ip add,1433; user id=uid; password=pwd;"
"Data Source=machine name; user id=uid; password=pwd;"
but the appliation always throws the 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
what is the problem in the connection. Do I need any special configuration that has to applied on the DB machine.
Anyone pls give a solution ASAP.
thanks in advance
