Your question does not have anything to do about using ipsec as far as I can
tell but yes you can set it up to work correctly.

--- Make the W2003 server domain controller and DHCP server. Configure it to
forward to the ISP DNS server for internet name resolution for the domain
clients. Disable DHCP on the router device but it's IP will be the default
gateway for all your computers. The domain controller must have a static IP
and point only to itself by it's static IP address for preferred DNS server
and all computers you want to join to the domain must point ONLY to the
domain controller as their preferred DNS server. The link below explains
almost everything you need to know about using DNS in an Active Directory
domain. As you learn how to troubleshoot become very familiar with ipconfig,
ping, tracert, and the support tools netdiag, dcdiag, gpresult, and gpotool.
Also make it a habit of using Event Viewer quite a bit to check on the
health of your computers. --- Steve
