Screen Saver Runtime Error

Hi
We enabled default screen saver using GP across our network but some systems are getting MS Visual C++ Runtime library. Abnormal Program termination. This error occurs as soon as the screen saver gets invoked. This occurs only for some computers, OS and Hardware is the same for all the client PC. Any help would be highly appreciated. Clients are all Windows XP and the DC is Windows 2003 server.

Regards
Sathya.
