when a DC is restored from the system state (amongst
others):
* the restored RID pool is thrown away (invalidated) and a
new RID pool is requested at the RID master
* the invocation ID of the AD DB is changed (which prevent
USN rollbacks)
so in your case it works because the backup is not that
old. The AD DB is tightly coupled with the registry and there is a reason for
that! The reason as why you MUST restore the system state as MS says. The way
you are doing that is, how shall I say it gently....NOT SUPPORTED!
;-)
And I guess you will be hitting on USN Rollback. See my
blog and search for BACKUP and you will find an article with some more
info

Subject: [ActiveDir] backup and restore AD.Hello,I had question about D backup & restore.It is possible to backup AD in 2 ways:1) backup only the system state.2) backup system state & file system containing the AD working directory (ntds.dit, edb.chk, Edb*.log,Res1.log and Res2.log).MS states that u have to restore your AD by restoring the system state.But ,what about just restoring the AD working directory without system state ? I tested it and that works fine.So my question is:=> In what circumstances do i have to choose a restore from system state or a restore from AD working directory.Thanks for clarification,Yann
