After reboot, Terminal Server on w2k3 does not allow RDP (just closes out)

Hi all,

After rebooting Windows 2003 Terminal Server (After a bunch of MS updates), I cannot login with RDP. The screen comes up (gray background as normal) but no LOGIN BOX! Just shows gray background and then closes out.

What can be wrong? I rebooted three w2k3 servers after updates, and only this one disallows RDP… It just closes out instead of loading Login Box…
