Simple Step : Enable DHCP Name Protection in Windows Server 2012 R2

August 10, 2014

What Is DHCP Name Protection?

As a Server Administrator, you should protect the names that DHCP registers in DNS on behalf of other systems from being overwritten by other systems that use the same names.

You should also protect the names from being overwritten by systems that use static IP that conflict with
DHCP-assigned addresses when they use unsecure DNS, and when DHCP is not configured for conflict detection.

For example, Linux system named OSI-CL01 potentially could overwrite the DNS address that was assigned and registered
by DHCP on behalf of a Windows-based system also named OSI-CL01.

A new feature in Windows Server 2012 R2 called DHCP Name Protection addresses this issue.

So lets see how simple you can enable this function…

1 – On OSI-ADDS01 domain server, open DHCP console, right-click IPv4, and then click Properties


2 – In the IPv4 Properties dialog box, click the DNS tab and then click Configure…


3 – On the Name Protection interface, click Enable Name Protection check box, and then click OK 2 times…


Thats all what you need to do to enable DHCP Name Protection in Windows Server 2012 R2.

Wait for my next post, how to configure DHCP failover in Windows Server 2012 R2…
