Running Product Config Wizard on WFE throws Exception: System.Data.SqlClient.SqlException:

When I tried to kick off PSConfig on WFE, I receive the following error:

Task upgradebootstrap has failed with an unknown exception<o:p></o:p>

Exception: System.Data.SqlClient.SqlException: 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 was able to test that I'm able to connect to Database from the WFE by creating a udl file.

Made sure that Named pipes and tcp/ip is enabled on the SQL server...

Any help would be greatly appreciated.

Thanks
