DNS records from multiple network cards

Hi!

I have a Window 2008 R2 server with more than one network cards, each for different purpose, the server is a DC.

The problem is that for each network card, it creates an A record in the DNS, but I only want a single record for that server (only one network card).

I've uncheck the option "Register this connection's address in DNS" from the DNS tab inside avanced settings from the IPv4 protocol of the network card, but it keeps auto-registering in the DNS.

What else can I do?

Thanks for your help!
