WMIPRVSE.EXE Error When Switching Users

[Guest MSRX92]

Since downloading service pack 3, I've been getting a wmiprvse.exe error

"0xc0000409 occured in the application at location 0x46af7242

 

This error occurs when switching between logged on users. The error doesn't

appear to be affecting any functions. Anyone have any ideas on what is

causing this error and how to stop it?

 

Thanks.
