Hey how can i back up my GPO,AD Configs,and other user profiles for my switch to like sbs 2003

PS. we are switching becuse on this server we were using a trial copy of 2003ent and we tried sbs earlier and are switching to sbs

Hi there.
Are you installing SBS on a different machine or the same one? If it's a different machine then install the server and join the existing domain - all the GPO's and AD info get's copied across automatically. Make sure you transfer the 5 FSMO roles to your new server before you demote the old server.
If you are going to be using the same server then the above is still by far the easiest way to transfer the data. Install server 2003 on a desktop PC and join your current domain to store your settings temporarily.
Hope that helps.

You won't be able to join an SBS machine to an existing domain. The SBS machine must be the first DC in the domain.
Check out the Group Policy Managment Console, where you should be able to export and import the Group Policies.
