Windows 7 Print Spooler

Hello Friends,

i am facing a strange issue that on some clients of windows 7 print spooler service keeps stopping and on start gives error message "Windows coudn't start the Print Spooler service n local computer. Error 0x80010057: 0x80010057" .

When i change   RegisterSpoolerRemoteRpcEndPoint vlaue from 1 to 0  at  HLM\software\policies\Microsoft\windows nt\printers ........  but after restart or group policy update problem comes again.

I am fed-up from this issue please help.
