only homemade servers should have the "unpure"/kick problem. If you used deviance.net to get this server, chances are you made it from home, so you just need to set sv_pure 1 to 0. It's in the .bat file. Just right-click, edit, and set sv_pure 0. Your server will be unpure, but it's the only way people can connect. Of course, as long as you put in noghost 144, it pretty much balances out the unpure part.
