Reverse Zone on DNS will not update automatically


I have a network that has DNS on a Windows 2008 server, the DHCP is on a router.  The DNS was not working correctly and had old addresses and some address duplicated.

I turned on Dynamic updates (secure and non-secure) and the salvage for 7 days.

I also put in an auto logon script to perform and ipconfig /flushdns and ipconfig /registerdns

The dns forward zone updates but not the reverse zone.

All clients are windows 7
The clients that have a fixed ip address do update the reverse zone.

I deleted the reverse zone and recreated it.  No updates for DHCP enabled clients.

Any ideas how to have the PTR records to automatically update?
