I am having issues with TW2002 with the game server kicking a user who is being attacked out. It doesn't seem to happen with any other users interacting, just with these particular two. I cannot figure out what is wrong with the thing, and it keeps saying that it cannot access TWUSER.DAT to get things to work..

Try deleting the twmail.dat file in the directory for that particular game. I have had other issues that affect anything from 1 to all users and I have found that this file causes problems from time to time. All that is contained in here is the user mail and messages, it will be replaced by a new one so dont worry about loosing anything of importance. You may have to stop your server to delete it tho.
