We have a new customer running SBS 2003 SP2 (standalone) whose AD not working. At first glance it looks like the cause is the fact that the AD integrated forward lookup zone is missing, so directory services won't start. Because Directory Services won't start I am unable to readd or restore the AD integrated zone.

Any suggestions on a fix?


Would this re add the zone?


Authoritative restore

Restore subtree “,cn=MicrosoftDNS,dc=forestDNSZones,dc=contoso,dc=com”

Look through the event log and tell us any pertinent errors that are there. Event IDs can be a big help. – Wesley Dec 24 '09 at 17:55
