My DC's are also DNS servers and run Server 2008 R2. I recently noticed that I couldn't resolve IP addresses to host names for most of the hosts on my network. I checked my Reverse Lookup Zone for this subnet and found that only a small fraction of the hosts were listed. In other words, dozens of hosts can't be resolved in reverse because they are missing from the reverse lookup zone.
How can I fix this so that the reverse zone will be updated regularly with the correct information as hosts get new IP's via DHCP?
