SQL Server Access Problem

Posted on 2011-03-16
Last Modified: 2012-05-11
I just installed SQL Server 2008 R2 Express on a Windows 2008 server. When I attempt to access the server with SQL Server Management Studio, I get the following error message:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)

You should connect to <your server name>\SQLEXPRESS

Thanks for responding. However, I have tried your suggestion and I still cannot access the database with Management Studio.

Yes, I have 2, which maybe the source of the problem. SQLExpress and Doorways (the company name). I originally installed SQL Server 2005 Express and then installed SQL Server 2008 Express after removing 2005. However, it didn't seem to completely uninstall the 2005 version and one of the services is a reminent of the 2005 installation.

Please look into Programs and Features in Control Panel to find if any SQL Server 2005 entries are there.
Could you post results from following:

start->run-> (type) cmd

sc query |findstr "SERVICE_NAME"|FIND "MS"
