Please bear with me - I'm very new to SCOM, so I'm probably missing something really obvious here. I've got a fresh install of SCOM 2012 SP1 and I'm trying to add my first devices, and I decided to start with my switches. I used this guide and it all seemed to go fine, but I've since tried to force the discovery to run several times. It says it runs successfully:
And yet nothing ever shows up in the Network Devices or Network Devices Pending Management and, probably even more relevant, the Last Discovered/Last Pending/Last Run Time columns are always blank. Why isn't the discovery running?
