Call of Duty World at War Beta

I'm running a CoD:ww server on a dev box with xp. Runs perfect.
My box in my data center is server 2003. Moved all the files there, installed/update with dxwebsetup.exe and tried to start the server.. Will not start.
I see some hosts running it so I know it can be done.
Anyone out there have a suggestion?

Guess I should say it is the newly released beta version.

How do you run a server for CoD, i've always wondered, love the game play non stop
