Suddenly one of our W2K3 / domain controller / exchange boxes slowed down to a crawl with no real indication (event log) of why... Now anything I do on the server (view event log, look at Exchange queues, bring up the start menu, etc.) takes between 15-30sec to complete... CPU usage is low, highest memory process is Exchange Information Store using 23MB... any ideas on where to start on this one?
The resulting questionable event logs that I can see are:
Event Type: Warning
Event Source: W3SVC
Event Category: None
Event ID: 1013
Time: 11:28:52 AM
A process serving application pool 'DefaultAppPool' exceeded time limits during shut down. The process id was '4424'.
