Situation: The client has a duplicated PTR records and can’t delete them.
Troubleshooting: We recommand them to use powershell or CND command. Here is the example
dnscmd DNSServerIP /RecordDelete Reverse Lookup Zone X.X.X PTR
In our example, DNSServerIP = 10.0.0.84, Reverse Lookup Zone = 10.in-addr.arpa, x.x.x = 126.0.0 (the host IP is 10.0.0.126)
dnscmd 10.0.0.84 /RecordDelete 10.in-addr.arpa 126.0.0 PTR
