Yesterday we´ve had again this annoying thing which hunts rf2 since some builds ago. But this time i didnt let my arms fall down and go hunting what the $#%" is this that let server run ok sometimes and others wont. Result of my quest...... After checking several things i noticed that we were using one dedicated server but we were having two dedicated.exe processes running. For some unknown reason, sometimes when the dedi is closed it remains as a running process. Need to close it from task manager so when we open it again everything goes well. Dont know if anyone still having this issue but i felt i should report it here.
Not sure if same issue, but not totally SOLVED : http://isiforums.net/f/showthread.php/22055-Dedicated-server-GetMod-Passworded-server
