To log into Console 0 (the real desktop) of a Windows 2003 Server, run the Remote Desktop Connection client with the following command:
mstsc /console
Now I can totally remove VNC.
Use mstsc /? to see all arguments you can pass to Remote Desktop Connection. /v:<Server[:Port]> /console /f fullscreen /w:<Width> /h:<Height> /edit will open RDP file /migrate migrate old RDP files
Cool tip, but dang, it doesn't support multiple instances. For reasons I probably shouldn't list here, I leave my 2k3 server at a locked desktop. So I get rejected with a terse "you're already logged in as console" message.
