Discovered something today that I wanted to share. I tried to do an nslookup on several boxes and noticed that some of them were retrieving records and some werent. I checked dns and sure enough, not all ptr records were there for dynamically created A records. Turns out that I had to update the dns credentials that were on the dhcp server. I think the admin before me created a special account that was used for dns updates but the account no longer exists. After I gave it to correct credentials, ptr records started showing up for clients that renewed their leases. Just an fyi.

Configure DNS dynamic update credentials: Dynamic Host Configuration Protocol (DHCP)
