That does in fact appear to be the issue. That being said, how do I get those 48 unknown devices to be "known" or would those be devices that show up in inventory, but do not yet have an agent installed on them?

So I rebuilt SCCM 2012 on Current Branch and have all sorts of clients reporting in for Win7x64 updates, however some flat out stupid things are showing in the console. For example, I'm seeing that the update is not required for any of the 242 devices that SCCM has identified it is compatible with, but then % compliant is showing...67%! See attached screenshot.
