We have print server running on Windows 2003 Server. For last few days, printer spooler services are acting funny. When users are trying to print through print server, they get an error message saying that printer spooler is not running. When I looked at a service under administrative tools, printer spooler service seems to be running, but I would have to restart services so that users can start printing.

It seems to be happening in the morning, but once I restart printer spooler service, users don't that error messages anymore. I can't figure out why it's happening though. It only happens once in the morning for last few weeks, and there's more print jobs running in the afternoon, compare to the light printing in the morning.

Can someone please help
