I have a windows 2003 Enterprise server that was working perfectly fine in a cluster as of 3 days ago. Suddenly I noticed that it is no longer responding to logoff or shutdown commands. Nothing has been added to the system recently. The only difference I can think of is it is currently not the active node in the cluster (which it usually is). The strange thing is after I click shutdown and restart, it will not let me run any other applications yet it will not restart. I've waited over an hour to see if it would but it just sits there. Any help would be appreciated.
