Missing System Restore

[Steve Lambert]

Can any one help.
On Win XP the system restore has stopped working.
On Control Panel, Systems, there is no system restore tab
and when I try to run System Restore I get this error
message: The Procedure Entry Point
RemoteAssistancePrepareSystemRestore could not be located
in the dynamic link library WINSTA.dll

Help appreciated.
Thanks

Ramesh has suggested:

"Check if this can help:

1. Insert the Windows XP CD
2. Click [Start] [Run]
3. Type the following command and press Enter
"rundll32.exe advpack.dll,LaunchINFSection C:\Windows\Inf\sr.inf"

System Restore core files should be reinstalled.

Alternately, you may also open Windows Explorer, navigate to
"C:\Windows\Inf" folder and right-click sr.inf (choose Install)"
