The SID isn't based on the domain name, but all the indexes in the
tdb's are based on the domain name. So if you change it on the PDC
then you could (with effort - ie. I don't think we ship tools to
do this) modify these indexes to use the new domain name. I don't
think Windows clients can do this though - change the domain name
means a new domain for them.
