Randles, we figured that out a few pages ago and I believe everyone has adjusted their TCAdmin game configurations to match.
The problem some of us are having now with Server 2008 and Brink is that it will not run properly. In our case, just letting it run under SYSTEM or under a limited user account prevents it from starting properly. Humbug was having a similar but different issue.
One of our staff figured out that if we create an Admin account, and assign the game service to run under that, it will work. So the question now is, what windows user permissions are required for BRINK to actually start properly?
