On a Windows Server 2003 R2 server, the "server" service stops 2 or 3 hours after the boot of the server.When this appens I have no event in the System log. Then If I try to restart the service manually, I get the "Error 5 : Access is denied" and an event in the system log from the "Service Control Manager" : The Server sevice has stopped : Access is denied. After a reboot the service starts correctly but then stops again after 2 ou 3 hours. Has anybody got an idea ? Thank's.
