I'm able to get all of my machines to inventory properly, including our 2008 R2 boxes with the exception of one.  I've already done the 'all zeroes MAC addition' fix in the config file mentioned earlier in this forum, which helped keep my 2008 R2 boxes in OME.  Regarding the server, it will get discovered, but it places it unknown.  Any ideas?

Info to add: when running troubleshoot tool and using SNMP troubleshooter, it correctly returns the version of OMSA.
