I've recently installed Configuration Manager 2007 r3 on Windows server 2008 r2. The installation has no errors yet for some reason I can't see any of my workstations in the console. All I can see when I browse to 'collections - all systems' are servers. I've tried running the various discovery methods with both server and client firewalls temporarily turned off but still no luck. Does anyone have any suggestions to what could be preventing discovery?
