hi there.. well, i intend to migrate my NT domain to AD and with ADMT2, it works well. however, got this query... if my username after migration come with a prefix or postfix, then my exchange service account will be different, for example on NT4 domain is old\exchange and AD domain will be new\new_exchange. in this case, after i join my exchange server 5.5 to AD, how can i change the service account from exchange to new_exchange?
