Is there a way to move all the records into a new reverse lookup zone?

We currently have a Primary AD-Int forward lookup zone, but no reverse lookup zone was created.  Names do get resolved when doing an NSLOOKUP by IP, so I suppose it is doing this by NBT queries.  Anyway, I'd like to create the reverse lookup zone, but we have over 100 records in the forward lookup zone.  Rather than going into each record and checking 'Update associated PTR record', is there a faster way to do a bunch of them at once?

Are they all dynamically registered in the Forward Lookup Zone?

If they are you wouldn't have to wait long before the clients added in the Reverse Lookup entries if you create the zone.

Of course if you're talking about static entries it's a bit of a different matter.

We do have secure updates selected for dynamic updates, but all the hosts have static IPs... So, I don't know when they would re-register with DNS?

They'll still dynamically register unless you disabled it (which is actually quite hard to do).

It's worth checking though, create the zone, permit secure dynamic updates then run "ipconfig /registerdns" from a workstation.

If it updates correctly you should have all of them by tomorrow; default Refresh interval for dynamic registration on clients is 24 hours. The update is performed by the DHCP Client service, regardless of whether the IP is handed out by DHCP or not.
