We're using SQL Express because we don't own a Full license, we've ran Express since XD4, and besides Citrix still says they support Express and even bundle it with their ISO.
When PVS is installed, and Config Wizard ran, BROWSE button fails to detect the SQL Express server, and if I type in the server name, it comes back with:
“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)
I even tried installing PVS on the SQL Express server and it gets the same error. SQL was installed with all defaults.
I'm aware this isn't an SQL forum, just hoping someone out there in the Citrix community may have ran into this and know the fix.
