Iam running windows 2003 on server A and Sever B. Server B is a workstation and Server A is running WSUS for windows updates and has clients in its domain. I found out that all the clients of server A automatically gets rebooted most probably that is due to windows update and Server B also gets rebooted whenever there are any updates which requires reboot. Following is the error which i get in the eventlogs:
"The process winlogon.exe has initiated the restart of computer B on behalf of user NT AUTHORITY\SYSTEN for the following reason. No title for this reason could be found
shutdown type :restart"
and before this log there are event logs which says like update is sucessfully installed and reboot required, which clarifies that this is not virus activity and reboot is due to windows update. I also scanned winlogon.exe with symantec antivirus and found no threat.
I have enabled " No automatic restart for windows update" option in group policy, it is not working as it only works when a user is loggen on, otherwise it will automatically reboot the system.
My concerns are:
1. How can i configure WSUS so that all the clients wont get rebooted automatically whenever there are updates which require reboot, instead user should get a prompt for reboot whenever he gets log on that system.
2. How can i configure Server B to disallow automatic reboot.
3. Why Server A wasnt rebooted but all the clients get rebooted
Thanks in advance.
