This utility works with all versions of UT2004 from 3186 up to 3323, and will also work on future releases. It works on a probability search algorithm.
It patches the following files and will also un-patch (revert).
IPDRV.DLL - Server side patch which allows clients to join without the
patch installed.
ENGINE.DLL - Enables the in-game browser and searches the master servers
for servers running compatible patches.
