Scenario: SQL Server 2005 is installed on server SQLSERV. SQL Server Management Studio is installed on REMSUPP. When I attempt to log in to server SQLSERV from host REMSUPP, everything works and I can navigate around in my database. However, when I attempt to open a table, I receive the dreaded "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible ... (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)".
I don't understand the part where it says "The server was not found or was not accessible". Clearly it is network accessible, or I wouldn't have been able to log into it. On the server, remote connections are allowed, the database is up and operational, and when I log onto SQLSERV and attempt to open the same table, it opens.
I've spent the morning researching this but getting nowhere, including reading existing articles on MS support site and following them step-by-step. I've compared and contrasted settings on another SQL-server/support-host instance, and everything looks like it is configured the same. "sqlcmd -L" run on REMSUPP lists the server I am having the problem with. Firewalls are disabled, as this is an internal network with no Internet access.
Can someone suggest what else I should be looking for? Thanks in advance.
