Optimal solution for setting up internet sharing

i have one m/c with win2000 advanced server with ics enabled. it has two internet interface cards. the public interface is
connected to dsl router thro cisco pix 501 firewall. the internal network has one ad integrated dns server and domain controller.  I have two questions -

1. ICS is perfactly working fine. i am able share the internet thro internal machines if i give the ip address of internal interface of ics machine as gateway for other client machines. But RRAS with NAT is not working.  Pls explain

2. i am continously getting 7062 event in event viewer in my  domain controller which also acts as dns server (ad integrated). now ics m/c also acts as dns server this event is happeing because of some clash between two dns servers.
i have manually given the ip address to all the internal machines with preferred dns server as ip address of my ad integrated dns server including the system where ics is enabled. is there any configuration problem.

pls explain.

eagarly waiting for your help

regards

Any reason why you want to use ICS when you have the PIX?
If it was me I would ditch ICS and have the PIX as the gateway for all machines. Disable one of the NICs in the server and configure it to have a single IP address.

Otherwise, as the server is a DNS server, you should ensure that there are only one set of DNS servers in the network configuration - the domain controller. If you need to use external DNS, then don't configure it on the external network card, put them as forwarders in the DNS server applet.
