DHCP Name Protection in Windows Server

If update-conflict-detection is on, Server protection is working. A Records
with no DHCID/TXT is safe.
If update-conflict-detection is off, Servers can be overwritten! ignoring
DHCID/TXT existence.

If your Server people start to setup their Servers with DHCP, the DHCID is
still the ID of the Server and dhcpd will overwrite the A Record if any
other client comes along with the ServerName!

I disabled DDNS for dynamic addresses from ServerLans.
