I have configured SNMP correctly I think. And Server Administrator is correctly installed and functioning. My problem is that the servers have two cards, with ISA server and the MS firewall runnning in between the two. The only services available on the external card are web and email related. I have configured the MS firewall to pass UDP and TCP 161, but don't know what I'm supposed to do (if anything) to ISA. I believe that the problem is with ISA as I have a similar server up and running perfectly with the same configuration, but no ISA server installed.
Thanks for the quick reply.
can you ping the management server - i.e. is there a route back to you management station - i have never used isa but usually on firewalls your default route is the external router to the internet? also have you tried disconnecting from the internet and then completely opening the firewall up (everything allowed) just to see if its a port blocking issue.
