Well I have no problem with XP Home running as a server. There were problems
initially with just how much M$ had stripped until someone pointed out that
people could not access their work systems from home ;) The only problem I
currently see remaining is that I can't connect to a windows domain from a
Home machine - only to workgroups.

What are you ACTUALLY updating? Version of the FB client or just an
application? Have you tried running with the old client but the new
application ( I have W98 clients still accessing FB2 with an older client and
working fine ).

Need to know some version numbers of the bits that work and that don't.
