As the DHCP servers in this environment are Linux based we would like the clients to update their PTR records themselves.
Updating the PTR records means a client registers his name and IP in the reverse lookup zone.
Had to troubleshoot a workstation hogging bandwidth.I just manually deleted any old entries that were not uptodate. I have triple entries on the same IP and all 3 entries are wrong (they don't match the forward at all).I deleted an entry from the reverse on a machine that receives DHCP, but after 2 days, it has not re added the machine into reverse DNS.However in the past I have seen strange behavior with the GPO settings below Administrative Templates\Network\DNS client section, and today was just the same. Below Computer Configuration DNS Client there is a setting called “Register PTR Records”.One could think that this is pretty easy to configure, enable, throw a gpupdate in and off we go.
