I've been struggling with the problem of previous NT PDC and in my case,
trying to figure out how to keep it online while I ease the transition.
It appears to me that the 'vampire' tools is a monster, and how you deal
with it is left to the imagination of the admin.

Anyway, to answer your question...
'net getlocalsid' will tell your your Domain SID
'net setlocalsid' will allow you to change it to whatever you want but
recognize that the accounts created by the 'net rpc vampire' will all
have the localsid (SID) set by the value that is in your new account
script, which in my case - was the smbldap_conf.pm YMMV.

Thus, if you want the users to use your new domain's PDC, they would
have to have the correct SID.
