  Unless you are running SBS, don't even try to do that. It will cause all sorts of odd problems. Do not use a DC as a router. Do not give it two NICs.

Depends on what you want to achieve. Is your network curently connected to the internet? If you have a DNS server in your network then that server will manage all DNS queries for your network. You should have 2 DNS and 2 DC for redundancy purposes.

Again nowadays routers like Linksys, netgear, etc, can do dns, dhcp, ftp and other network services. So a router is recommended in your situation.

You could setup a server to do routing and other functions like VPN if you have resources. Below you will find information required to do that:

Hi Jeba,

Thanks for posting here.

Enabling NAT feature on a RRAS installed serve host with duo NICs is the way for us to play it as the internet gateway of internal network. The introduction could be acquired form the article below:

And we should set DNS forwarder or using root hits on internal DNS server in order to implement internet name resolution for internal hosts if this is an active directory environment:

Bill si right. You should not try to use DC that is multihomed. More details here : http://blogs.dirteam.com/blogs/acefekay/archive/2009/08/03/multihomed-dcs-with-dns-rras-and-or-pppoe-adapters.aspx

You could try to setup a separate machine as a router (RRAS), but routers today are cheap and are a better option.
