When I run OMSA prereqchecker on a WS2008 Core machine with both Broadcom & Intel NICs, the report says to install Broadcom SNMP & Intel SNMP. The Intel SNMP installs without any problems, but the BC SNMP installer errors out complaining that it requires .Net 2.0. .Net 2.0 is not supported on Core. Per Dell support, install Microsoft SNMP (via OCSETUP) but not Broadcom. Did so, and everything appears to be normal in OpenManage Server Administrator.
