DHCP and dual NIC

Posted on 2006-04-25
Last Modified: 2012-05-05
I have a 2003 Server with two NIC's - one is wireless and the other is CAT5. I would like to use this server as a router and DHCP server, but I only want DHCP to run on the CAT5 NIC. The problem is every time I enable the 2nd NIC the DHCP services stop.

The desired config:
<SERVER1 - Wireless LAN NIC [] > ----> to Firewall / Internet
<SERVER1-  CAT5 NIC [] > ---> DHCP server to 192.168.10.x LAN.

Basically the 192.168.10.x subnet is my test lab w/ 8 clients, and I need them to use SERVER1 to get to the Internet.

    First, you need to make sure the wired NIC is at the top of the binding order.
    Next, you open up DHCP and configure it to only service the address.
    Finally, make sure the wired NIC is set to your own DNS only.

    Make sure the Wireless NIC is configured as follows:
    1)  Uncheck Client for MS Networks
    2)  Uncheck File and Print sharing
    3)  On the WINS tab (properties of TCP/IP) - disable NetBIOS.
    4)  On the DNS tab (properties of TCP/IP) - uncheck the option to register in DNS.
    5)  Remove ALL entries in ALL containers in ALL zones on your DNS.

    This should be all that's required.
