An awesome admin told me about a cool trick today... Needed to add a SQL Alias to SQL 2005 via SQL Server Configuration Manager. However, upon starting SQL Server Configuration Manager, received the following error:

Cannot connect to WMI provider. You do not have permission or the server is unreachable. Note that you can only manage SQL Server 2005 servers with SQL Server Configuration Manager.

Invalid Class [0x80041010]

Well, removing and reinstalling the SQL components was not a good option in this case. The solution?

Run c:windowssystem32cliconfg.exe

This is a SQL Server Client Network Utility that allows you to access some of the basic SQL Server Configuration options.
