I have two Windows 2008 R2 nodes that are behaving differently with Orion. One of them has Domain/Public Firewall turned ON and Orion passes the SNMP test. The other has the same Firewall setting, but FAILS the SNMP test. I checked the 2nd box and verified that UDP Ports 161 was allowed in both Inbound & Outbound rules. So, I am baffled. If I disable the Domain/Public firewall on the 2nd box, SNMP works fine.
How do I troubleshoot this problem further? TCP port 161 is not mentioned in the Inbound/Outbound rules. Any help is appreciated. Thanks.
