We're using OpsView/Nagios to monitor our servers. We've added the SNMP service to all our servers and deployed the configuration via GPO, but one win2k3 server seems to have a problem; it crashes pretty regularly. The event log carries messages like:

Event Type: Error
Event Source:   Service Control Manager
Event Category: None
Event ID:   7034
Date:   	6/11/2009
Time:   	7:11:49 PM
User:   	N/A
Computer:   HOSTNNAME
Description:
The SNMP Service service terminated unexpectedly.  It has done this 2 time(s).

and also

Event Type: Error
Event Source:   Application Error
Event Category: (100)
Event ID:   1000
Date:   	6/11/2009
Time:   	7:11:18 PM
User:   	N/A
Computer:   HOSTNAME
Description:
Faulting application snmp.exe, version 5.2.3790.3959, faulting module ntdll.dll, 
version 5.2.3790.3959, fault address 0x000417af.

Now, I could probably set it to simply restart on crash in perpetuity, but I think it's better to fix problems like this. Is this a known problem? If not, what should I do to diagnose it?
