Issue with multihome setup Server 2008 R2 using two NIC's

I hope someone can help with this cause it is driving me crazy.

I have a server Using Windows 2008 R2 with both NIC's enabled. The reason is I need IP assignments for data side and assignments for VOIP side. I have it configured as follows:

Nic 1 for data:
IP: range
DNS 2: (for second domain controller - which does no DHCP)

Nic 2 for VOIP:
Gate: Nothing entered
DNS1 and 2: Nothing entered

The issue is that I can go on a server and ping the primary DNS server and it kicks out the VOIP IP - and I want it to do the data. I have already check the properties on that NIC and unchecked it from listing in DNS, but it still manages to find it way in there. Everything runs great when I delete it, but when it shows up things slow down and take forever to process.

Is there anything I can do so this does not show up in DNS? I have tried removing it from DNS, but it continues to come back.

Any help is appreciated. Let me know if further info is needed.
