Folks, it is possible to join a domain once MCE is installed. It's kind of involved, but if you follow along, it's pretty easy.
Here are the instructions i followed, hacked out of a Google groups message board (link below!)
1.. Insert Windows XP CD.
2.. Start > Run > X:\i386\winnt32.exe /cmdcons
(replace X: with the appropiate drive letter)
3.. Acknowledge prompt by clicking 'Yes'.
4.. Skip updating process by clicking 'Cancel' or by pressing 'Esc'
5.. After installation, acknowledge success msg. by clicking 'Ok'
6.. Start > Shutdown > Restart
7.. At boot menu, select 'Microsoft Windows Recovery Console'
8.. Select proper installation to log onto (default: 1) and press 'Enter'
(If prompted, enter Administrator password and press 'Enter')
9.. Type (without quotes) and press enter: 'cd system32\config'
10.. Type (without quotes) and press enter: 'copy SYSTEM C:\'
11.. Type (without quotes) and press enter: exit

Like i said, i have sucessfully done this in the past, just remember, joining a domain messes up the Extender service in MCE (because it disables fast user switching).
