Not sure how many here may run with XP media center, but anyone that does and who runs with domains for their networking will find that they can ONLY join a domain during setup. I missed this during my install because there was no network present during setup! I have since found there is a hack for this situation. I am about to try the hack. If and when it works I shall post a link for it here. In the meantime - has anyone else here made this change?
