Disable Dynamic DNS update

Solution Verified - Updated -

Issue

Server A has IP address 192.168.0.10 assigned and is registered with DNS as servera.localdomain.net.

nslookup of servera.localdomain.net was pointing to 192.168.0.10.

After adding a second NIC and assigning it an IP address of 192.168.0.20, the system sends a DNS update request to the DNS server, which modifies the IP address for servera.localdomain.net

nslookup of servera.localdomain.net now points to IP 192.168.0.20.
