I have a server that is currently running Windows Server 2003 R2 SP2. The last 2 weeks or so we are experiencing random shut downs with the server. It is going through a full shut down process. In event viewer you can see these shut downs and this is what they say;
"The process winlogon.exe has initiated the power off of computer SERVER1 on behalf of user SERVER1\Administrator for the following reason: No title for this reason could be found
Reason Code: 0x0
Shutdown Type: power off
I've checked all the normal causes that I can think of such as Virus software, Automatic updates, Scheduled tasks, etc. There is no virus software on this computer. Automatic updates are turned off. And there isn't a single scheduled task. I ran a malware scan which found nothing.
One thing I will mention is that this server is a bit behind on updates. I am hesitant to do them as the client uses some specific industry software that he claims stops functioning after he updates with the current updates that are waiting to go through.
Any ideas of where to go from here?
