Server – prevent registration of multiple IP to DNS from one server


I have a server with two IP addresses, one for internal network, one for external. But my server registers both IP addresses to DNS, and computers on internal network, sometimes get connection timeout.
The problem was solved when I disabled the DNS registration on the other NIC.

Go to TCP/IP v4 properties on NIC

Hit button Advanced

In DNS tab remove check mark on Register this connection’s addresses in DNS

now delete the A record, from DNS, with secondary IP and flushdns on computer with connection problem.


Good Luck
