GW Server has critical error and reboots

We have Novell 4.1 and 2 servers in the tree. We also have 2 GroupWise servers (one at each location). Our main GW server has been popping a message to users that it received a critical error and will shut down in 2 minutes. Then it shuts down and reboots itself.

Does anyone know what could possibly be causing this? Both GW servers are running the internet agent, etc. The problem server is a new PC. Could it be that it doesn’t like some driver or something with netware or GW is bumping headswith something else?

Our manager has rebuilt the GW on both servers from the top down and it still keeps shutting down.

Any suggestions? Thanks in advance…
