I'm fairly sure you can simply upgrade this domain with the underscore 
in place... email me off-list for more detail but AD domains have a 
NetBIOS name (which would still be compatible) and DNS names which can 
be completely different to your current name.

It isn't a bad idea to start afresh though - the ADMT tool (Active 
Directory Migration Tool) is usefull for migration users, computers and 
critically profiles across and it doesn't suck entirely. Also it 
migrates the users SID to the new domain.. Samba uses the winbind 
uid/gid cache to identify users, and I'm not too sure how moving the 
account will impact it

Thanks
