Multiple PTR records, different hosts for same IP?

[WhoKilledKenny]

Issue: In the Reverse Lookup Zones in DNS I see multiple records for a singe IP:
192.168.165.10 Pointer(PTR) Computer1
192.168.165.10 Pointer (PTR) Computer5
192.168.165.10 Pointer (PTR) Computer7

I see this in both Static and DHCP subnets.
In the Foward lookup zones to the hosts have "Update associated pointer (PRT) record" -Checked.

The issue is causing a problem with an Application that does a reverse lookup on the host. The first time it does a lookup, all is well as it returns Computer 1. When doing a second lookup it returns the hostname Computer 5, which causes the app to freak out.

Any help appreciated...

Also, DNS scavaging is enabled and set to 7 days.

You shouldn't have multiple PTR records for the same IP. Delete the incorrect ones from your DNS server.

ok... I understand that I can manually delete them, the question is how are they being created in the fist place. Also, there are many more entries then just the sample in this post.

Looks like I found the issue:
Scavenging was set on the forward lookup zones. When manually creating a reverse zone it doesn't set it up for scavenging. I have only set it up on one zone to test the outcome. If anyone knows of any issues with setting this up please let me know... I will research before implementing.

Thanks again...
