Domain controller Having Null IP address:
  When you do nslookup of your domain controller and if it resolves for 2 IP address and one IP address is like null value like if you try to delete the IP address manually also the entry will recreate in DNS.  Kindly follow the below steps to resolve this issue

> server1
Server:  localhost

Name:   server1
Addresses:, 10.x.x.x

1. Go to DNSmgmt.msc --> Properties --> Interfaces

Here only the following Ip address should be checked and in the IP address box the server correct IP should configured. If you see 2 IP address configured in the Interface console apart from oreginal server Ip address means remove it and restart the server.
