    @zippo: Couldn't do sysprep image back onto domain as domain was no longer contactable or even working on the DCs. @Geoff: Would have liked to attempt the authoritive restore though, that may have saved some time. @Davit2005: The GPO shouldn't have been but something went wrong and that must have been the cause.

    All is well and working fine though so no lasting harm done hopefully I won't see any other issues developing from this.

    As an aside if both DCs died you would have to restore from backup would you then do an authorative restore on each of the DCs to sort out the time problem?

    No you pick one DC and tell that to do an authoritative restore. You then rebuild the other DCs from scratch and they will pick up everything they need via replication when you join them to the domain and promote them to DCs. But the whole point of having multiple DCs is to avoid this sort of situation in the first place.

  4. Thanks to Geoff from:

    authoritative restore
    Thanx, I now have confirmed my thoughts on the difference of the two restore methods :-D

    @Geoff: If only life were that easy . So authoritative restore on a DC preferably the one with the most FSMO roles then create new ones add them right lets hope this never happens again.

    Thanks guys,
