DNS question on Mulitple Network Cards and Exchange Server

I have an Windows 2003 Exchange Server with Mulitple Network Cards!  We are only using one of the card (No teaming), but both cards are plugged into the network.  My question is that in DNS the Exchange Server Name (A record) is showing up twice.  Once for each network card.  Will this/can this cause any problems?  If so should I just unplug one of the network cards from the network?

Turn off one of the network cards unless you need a network bridge or have them teamed for faster throughput.

Should I do this "after hour" or does it matter?

It really shouldn't matter, but it probably will. See which IP address is listed in DNS with an MX record. Disable the other
