Error while establishing a connection to the SQL server 2005 - Could not open a connection to SQL Server
Hi,
I had an old web application created during asp.net 1.1 and it have a connection problem with the sql server 2005 when it is mirgrated to a new webserver with dotnet framework 2.0 platform. I have enabled the remote access(TCP/IP and named pipes) in sql server 2005, did all the neccessary things, check whether the TCP/IP is enabled, named pipe is enabled...
I created another web application using VS 2005. The database connection works perfectly well.
This are the connectionString from the old web application.
<appSettings>
<add key="ConnectionString" value="Server=127.0.0.1;Database=somedb;User id=user; Password=somepassword; Trusted_Connection=False; POOLING=FALSE"/>
</appSettings>
Thankyou in advance!

I am not sure but maybe try this?
<appSettings>
<add k ="ConnectionString" value="Server=127.0.0.1;Database=somedb;User id=user; Password=somepassword;"/>
</appSettings>or
<appSettings>
<add k ="ConnectionString" value="workstation id="computername";packet size=4096;data source=yourserver;initial catalog=yourdatabase ;user id=user;password=password"/>
</appSettings>
Thanks

Could you provide code where you use your connection string? How you read it from config file and how you use it to get data?
Thanks

Hi,
This error message is just a basic connectivity error meaning the client could not connect to the target SQL Server. So just follow the basic connectivity troubleshooting guidelines on our SQL Protocols blog, see:
SQL Server 2005 Connectivity Issue Troubleshoot - Part I
http://blogs.msdn.com/sql_protocols/archive/2005/10/22/483684.aspxand
SQL Server 2005 Connectivity Issue Troubleshoot - Part II
http://blogs.msdn.com/sql_protocols/archive/2005/10/29/486861.aspx
This should help you debug the problem.
Sincerely,
Kevin Yu
