I downloaded the trial VHD from MS, loaded up on a Windows 7 Virtual pc system. Once the windows server 2003 comes up, I install AD, DNS, and DHCP on a test network. Then I install SCE 2007. Once it comes up of course it sees the server itself. I then added test XP to the test domain. DHCP, DNS and AD works, the XP shows up in AD fine. Once I try to discover the xp nothing. No matter if I tried local admin or domain account. What else am I missing?
