Hi,

I have Windows 2008 R2 and running SQL Server 2008 R2.
When adding a web part manager to my page and run it gives me the following error:

Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
