I have tried the suggested options of -nv, -w3d, setting video_mode and video_screen to 0, but no solution.

I want to run the server on a Windows 2003 root server, and these come usually without a 3d graphics card. I have 5 servers running at this time, and on all the test server package refuses to run.
Should I change to special (probably expensive) servers with 3d capabilities or is there another way ?
