Hello guys,
I have a remote site with one Domain Controller/DNS Server. This DC has two NICs - one for the production connection and one for the backup. Production connection uses its own IP as preferred DNS server address and one of the hub site DC's as a alternate DNS server. Backup
connection is configured not to register its IP address to DNS and it doesn't have any DNS server addresses configured.
DNS server is listening production NIC IP address.
Yesterday I was notified by a college that one application was failing because reverse DNS query for this remote DC was not returning any result.
When I started investigating, I discovered that Reverse DNS zone actually
was missing PTR record for this remote DC. All other Domain Controllers in other
sites have PTR record registered. Also, production NIC had option
"Register this connection's addresses in DNS" UNchecked.
Next I used following PS command to enable automatic registration to DNS:
Get-NetAdapter -Name "Production" | Set-DnsClient -RegisterThisConnectionsAddress $true
It's now more than 24h since I enabled this setting on the remote DC, but I still
can't see PTR record registered on the reverse lookup zone. I was contemplating
should I run ipconfig /registerdns, create a static record or wait even longer? If I run ipconfig /registerdns command, could it cause duplicate entries to DNS since it affects all NICs right? Still I think waiting doesn't change a thing and manual intervation is now required.
Please help how to get my DC register its PTR record to DNS.
