Restarting Server Help

[Darrien]

So we have a friend who is able to host the server on a unused server at his work, and since we use  about half a dozen mods they update every so often forcing a restart. I can shutdown the server in game but I can't restart it in game, even if you hit quit in the server console the exe is still in the background, and we have both been trying to find a way to restart the server automatically with a scheduled task so we do not have to bug him to restart it each time. Does anyone have any ideas?
