frequently (up to 4 or 5 occurances in 8 hrs, seems random) my computer
restarts. I get a 'System Shutdown' window with a countdown timer stating
that the 'shutdown was initiated by NT AUTHORITY\SYSTEM' and 'lsass.exe
terminated unexpectedly with status code -1073741819'. the restart can be
aborted with the command 'shutdown -a' but this invalidates my domain login.
i'm running xp pro sp3. appreciate any help i can get to correct this.
