WSUS for SBS2003 hates me :p

Before I leave my old job one of my to-do's is to configure WSUS for the 30 machines here. Everything went all smooth and such, however I have no client computers being detected. Apparently this is a common thing, the issue being several things. The problem is no one seems to have a definate answer to why this happens.

I have tried everything from changing the anonymous access on the default website, creating and adding GPO's for my workstations, and now I am trying to change the port incase its interfearing with my Sharepoint website port 80.

Here is the minimal info I have found.

Ill update this with what works.

Default WSUS 2 in SBS? Or updated to WSUS 3?

Have you changed your rigs to other than the default SBS OUs?

gpresult showing anything on the workstation side?

Post the windowsupdate.log from one of the clients.

Did you point the workstation to the server name in the GPO?
