I have a windows 2000 and 2003 dc's running AD integrated DNS.  I have noticed my reverse lookup zone that corresponds to my main user DHCP subnet I have many, many duplicate records resolving to various old machine names.  I saw that scavenging of stale records was not enable on this reverse lookup zone...but it was enabled on the corresponding forward lookup zone.  I have since enabled scavenging on the reverse lookup zone.  Refresh intervals are set to the default of 7 days.

Have I taken the right step to ensure my PTR records are current and only reflect the current information?

Yep, that sounds ideal. It will take a while for Scavenging to kick in, it's not exactly fast at running for the first time on a zone.

It seems as though I have scavenging set up correctly yet I still see many dupicate entries in my PTR records.  Some are quite old.  I am not sure how I can get them to expire and be deleted.

You may find it's quicker to delete the zone and let it start afresh. It's relatively unusual to find a reverse lookup zone with static entries in.

It's may be advisable to turn on Advanced (from View) then open the properties for a few of the records to check they have the box ticked that states they will be scavenged when they get old.

It's also possible to force-run Scavenging then check the event logs for errors (if any).
