I'm having problems with a server that has been restarting itself randomly for the past 3 months. The server is windows 2003 with SP2 Domain Controller and it is fully patched.
I have seen the following errors in event log:
Event ID: 1074
The process winlogon.exe has initiated the restart of computer (server name) on behalf of user domainname\Administrator for the following reason: No title for this reason could be found
Reason Code: 0x840000ff
Shutdown Type: restart
I have ran out of ideas as to what might be causing this issue. The system is clean and not infected. There are no scheduled tasks responsible for the restart either.
I'm considering moving the backup (Backup Exec 12.5) to a different server but I'm almost certain that this is not the issue as the restart times vary and do not match the scheduled backup jobs.
Any suggestions to help me resolve this issue would be appreciated, thanks.
