  • Removed the 'Store Zone in Active Directory' in DNS and all now seems ok.

    The Zones do not now appear in AD, have they been deleted physically or logically ?

    May try to change it back when the users have recovered from not having the Internet for a week.

    Many Thanks

  • how did you remove the store zone? detailed operations.

    only one DNS server? if you delete a secondary copy of a zone, or still copy of zone exist. it seems no big trouble.
