One of the servers that we have here at my work has an strange issue... About twice a month, usually a week to a week and a half into the month and the same at the end of the month it loses network connectivity. Everyone has mapped network drives on their PCs that access this server and when it "loses network connectivity", no one can access the mapped drives. You cannot browse to the server via the My Network Places shortcut on the desktop or connect via Remote Desktop to the server. When we go into our server room log into the server, everything seems to be in check. There are no error messages up besides "Error, could not print" because there are mapped printers on that server. The only remedy for this issue is to reboot the server. This is extremely annoying because we'll sometimes have to travel into work on a Saturday or Sunday at 7:00am just to press the "restart" button on the server.
We noticed that there is an entry in the System Log in the Event Viewer each time that this happens. It is shown below:
Date: 5/10/2007 Source: Srv
Time: 10:23:50 AM Category: None
Type: Error Event ID: 2019
Computer: (our server name)
The server was unable to allocate from the system nonpaged pool because the pool was empty.
