Only way I know is through a macro which you dont want because it will take mouse and keyboard functionality, but if the server is a stand alone server hosting the games, the loss of keyboard and Mouse control shouldnt matter every 2 minutes. You could create a series of tasks in windows task scheduler to trigger every 2 minutes.
When I had my UT99-DM Server running macros, I had it stand alone for this main reason ( loss of keyboard and mouse ).
As far as BATCH... I dont know of any batch that could be made unless you knew the service to start and stop and available switches /r /s etc that are supported for a forced configuration. Then if you could make a batch that did this every 2 minutes, you would need the CHOICE command with a timeout and goto loop to have it in a closed loop like a TSR ( Terminate and Stay Resident )
I'd contact the company that made the game and ask if there is a configuration or database file that can be forced to a value for a parameter from its default value. Then upon the next map loading it should be fixed.
