Vista Network and Sharing Ctr Frozen

Can anyone help unlock this mystery?
When I click on Network and Sharing Center' I get the following
Network and Sharing Center
Unknown
Server Execution Failed

Sharing and Discovery
Network Discovery Off
File Sharing On
Public Folder Sharing On
Printer Sharing On
Password Protected Sharing Off
Media Sharing Off

I cannot click to change any of these buttons.
I have to Control Alt Delete to close the page.
I haven't been able to get any solutions to get this page working properly.
Any ideas out there.
Thanks

 

Problem Solved!!!

You're at the top of The Rock.
