Service Pack 4 for Windows 2000 is a good idea, not just for our game but for general purposes. Service Pack 4 has many o/s enhancements as well as fixes. It may not directly fix the problem that may be arising in DAoC, but it will certainly improve your chance of success to play the game. You can download Service Pack 4 by clicking on the Windows start button and then clicking on "windows update".

Bear in mind that, while many users have been successful running DAoC under Windows 2000, this operating system remains unsupported. Any changes you make to your system in an effort to get DAoC to run you make at your own risk.
