I have implemented SCOM 2012 SP1 CU5 on Server 2008 R2 with SQL 2008 R2 all installed on the same VM running side by side with SCOM 2007 R2 v 6.1.7221.0. I have almost fully decommissioned SCOM 2007 and all that remains on it is 2 network devices that I cannot discover with SCOM 2012 using SNMP, no matter what I try. If I just use ICMP the discovery works. I have checked both the devices and SNMP is enabled and if I run this snmpwalk command on both devices I get a response;

The first device is a Marms UPS which has had its firmware upgraded, which was discovered using SNMP in SCOM 2007 and the second device is a Juniper SSG-140 Firewall, again this is discovered using SNMP in SCOM 2007.
I believe that I have setup SNMP correctly on SCOM 2012 because I have 28 other networks devices discovered using SNMP using an explicit discovery, some of these being newer Marms UPS's, emerson air conditioners, netapp SAN etc.
I have added any and all accepted community names in the SNMP service properties on SCOM 2012 and enabled accept SNMP packets from any host.
Does anyone have any information that they could forward to me or point in the right direction to troubleshoot this issue for eg run some snmp get commands and capture / filter traffic with wireshark, what do I look for? Any other logs to check besides the obvious ones? Any known issues with SCOM 2012 SP1 and SNMP, should I upgrade to R2? It just seems that some network devices get discovered with ease and others do not and I am running out of ideas. Thank you all in advance.
