Unable to view SQL Server services Whenever I enter SQL Server Configuration Manager and choose SQL Server Services I would always get the following error message: "The remote Procedure call failed. [0x800706be]"
everything else works fine but not able to configure SQL Services anymore. has anyone came across this and managed to fix the problem?
If you are still running RTM (or SP1 or SP2 I guess), SP3 was released recently - give that a try and see if it helps fix the Configuration Manager issue. 

(Applying a service pack has helped others in a similar scenario.)
