Preserving profiles between server change

Hi

I need to disconnect win xp client pcs from an old sbs 2003 server and
connect to a new sbs 2003 server. The local domain name and usernames on the
new server would be same as before. Is there a way to preserve the previous
network user profiles on the win xp PCs?

Any other tips when connecting win xp clients to a new server?

Many Thanks

Regards
