i've gotta problem setting up a new custom service in windows 2000 server.

i'm attempting to get a hlds (half-life) server to run as a service so that it doesn't take up desktop / taskbar space and would be somewhat fault tolerant (restarts itself). i'm trying to setup the thing to take a set of paramters and start as a non privelaged user but when i try to put that information into the mmc service manager it tells me file not found. i know its refering to some registry key but i'll be damned if i know what keys it wants. does anyone know where i can find a REAL good faq / readme / tutorial on how to add custom services to 2k?

any assistance is appreciated!

TIA
