windows XP home can't join a domain, that's something exclusive to pro.you can have it as part of a work group though.
This isn't entirely true. While XP home can't actively participate in a domain as a full fledged member, it can be made to function in it. There is a registry hack out there someplace that I ran across a few months back that allows XP home to participate in a domain. Spent a bit of time working google and you should come up with the solution I mention.
Printing is still an issue. I have the printer setup on the SME Server \\server\minolta and can add it but after a reboot I no longer have access and have to delete and re-add it.Any suggestions?
