I hope I'm in the right forum. Can anyone tell me where I can find detailed instructions that explain how to use SMS 2003 to deploy Windows patches? So far I've only been to find technet articles that give tons of useless overviews of the patch management process, but no instructions on how to actually do it. I need to cut through the BS and get to step by step instructions on how to setup the packages, advertisments, etc. We basically want to start pushing out MS patches out on a regular basis. We have SMS 2003 installed on a Server 2003 machine. Thank you for your help in advance.

Consider ITMU. This page includes the tool, documentation, and videos. Should be what you need.

How many machines are you looking to patch? Depending on your size and reporting requirements (security audits?) WSUS might be an easier solution. I have used ITMU and it does work and scales very large, but might be overkill for your needs.
As for ITMU help, look for one of Microsofts Webcast. I have watched a couple of step thoughts.
