Windows Server 2008 r2 Domain Controller and multiple NIC ?

Hi.
We have a new Windows Server 2008 r2 being set up as a domain controller.  There will be two of these on our network.  Each has 2 NIC cards.  

I was assuming that we could have both NIC's connected to our network for redundancy, each NIC with a unique IP.   However, a network guy here said that you don't want to have two IP's on one Domain Controller.

Is this right?  It seems weird that any server made for a high-availability network would be limited to using only one NIC...

(I was looking online for some documentation about how to use two NIC's on one DC, but haven't had luck.)

Thanks for your input.

Thanks, I will pass this on to the other guys here working on this.
We do indeed have 2 DC's (and a second redundant device of everything else) in two different buildings, so that may mean "teaming" is overkill for us.  Even though we have less than 50 users in 3 locations here, we may end up deploying "nic teaming" anyway, just for the experience.
Thanks for your insight.
