I recently migrated some DHCP servers from 2008r2 to 2016 and some of them are having issues registering DNS PTR records for DHCP leases. Servers are fully integrated DCs running DHCP/DNS/GC.
I receive this error in the event log (DHCP-Server 20322 -- Name Registration.)...
PTR record registration for IPv4 address [[172.19.1.241]] and FQDN PC123.XXX.com failed with error 9005 (DNS operation refused.
).
Also, in the DhcpSrcLog-DAY.log i receive these entries
31,05/16/18,00:01:29,DNS Update Failed,172.19.1.241,PC123.XXX.com,,,0,6,,,,,,,,,9005
and occasionally
31,05/16/18,00:01:00,DNS Update Failed,172.19.1.37,PC124.XXX.com,,,0,6,,,,,,,,,9004
The DHCP scope is set as it should be...
And under the DHCP server's IPv4 "Advanced" tab I have entered the credentials of a user that is a member of the "DnsUpdateProxy" group.
All of the forward look zones register just fine.
I simply cannot find anything on that event log I'm getting.
Looking for some assitance.
Thanx!
