Looking in the SolarWinds DNS Audit we have several IP addresses with multiple machines showing under the Reverse Resolve IP -> Domain Name field. In the one subnet I am looking at there are probably 15 IP addresses that are showing this. Anywhere from 2 to 5 machines are showing up.

In the DHCP logs it shows 32,05/19/10,16:59:01,DNS Update Successful but it is not correct. We looked through the DNS servers and saw one machine we are having problems listed correctly in the Reverse Lookup Zone but not the Forward Lookup Zone. In WINS it is also correct. We just ran SolarWinds DNS Audit on one of the subnets and it is a MESS.

Machines dont seem to be registering correctly. I did some digging into it the past few days and it looks like when a DHCP renewal happens the Reverse Lookup Zone is being updated but not the Forward Lookup Zone. I have done some Googling but havent found anything that has helped.
