I just moved our IP Monitor 8.5 instance from an old Windows 2000 physical machine to a Windows 2003 Virtual Machine running on ESX. The migration went good for the most part, and the only remaining issue is getting the SNMP alerts to work right. The SNMP Cold Starts seem ok, but the straight SNMP alerts are all down with a status of "The remote device failed to respond"
I don't have the luxury of knowing if these were 100% before the migration since the old machine is off and the license removed (parked). There are only two SNMP alerts that work - they all use one of two communities, which are called "CommunityA" and "CommunitB" (not real names). They all use port 161 and the OID is the same for system uptime.
I don't know a lot about SNMP and am wondering if I have to troubleshoot the communities somehow, but can't find them in any of the pages of IP Monitor. Any help is greatly appreciated.
