Question : Delete Static Reverse DNS Entries

We have a number of static entries in our reverse dns zone for PCs.  These PCs were upgraded from W2K to XP and now I'm seeing the XP machines in forward and two entries for them in reverse - one static and the other dynamic.  

For example in Forward - WXP-Machine1=192.168.1.115
In Reverse - 192.168.1.115 = W2K-Machine 1 (static) and 192.168.1.115=WXP-Machine1 (dynamic).  I have deleted the old entry, but it doesn't stay deleted.  

This is AD integrated with DC doing DHCP and DNS.  Scavenging is turned on.  Under 30 machines total.  

Would it work to delete the Reverse DNS zone and then recreate it?  Any other suggestions

Thanks

Answer : Delete Static Reverse DNS Entries

They come back as static records? That's quite surprising, if records are dynamically added they normally come with a time stamp value.
