Hi there,

If you suspect that if NetLogon service registers the wrong IP address you can try the below steps and see if they are helpful.

-Start the DNS Management Microsoft Management Console (MMC).
-Right-click the DNS server, and then click Properties.
-Click the Interfaces tab.
-Under Listen on, click to select the Only the following IP addresses check box.
-Type the IP addresses that you want the server to listen to. Include only the IP addresses of the interfaces for which you want a host A record registered in DNS.
-Click OK, and then quit the DNS Management MMC.
