Question : Server 2003 DHCP not working, probably easy question

I am having troble with the DHCP assigning an IP to my internal PCs.  I have set the scope however when I open up the admin tools and look at the server it says not connected.  When I click on it it then opens up and reads active, it still does not assign IPs though.  I am also trying to use DNS and WINS on the same PC.
The server has 2 nics.  One with an ip of 192.168.1.100 and the other assigned by the isp.  I have internet connectivity on the server but non on the other PCs, I have NAT installed.  As a side note I had this all working a few days ago I think either the DNS or WINS has taken it out.  I have all the services assigned to the 192.168.1.100 interface.  In routing and remote access I have NAT/Basic Firewall installed and it has a Wan and Lan interface intalled.  The lan has the box check for the internal network the Wan has the box checked for a public interface.  Under NAT/basic firewall  both DHCP allocator and DNS proxy info read message ignored on the first line.
I am sure this is something easy I am missing please let me know what you think it is before I buzz my PC out of the window.
Thanks

Answer : Server 2003 DHCP not working, probably easy question

What do you mean it does not assign IPs?  you have another computer that is configured to receive IP addresses automatically, and it is not?  What does it say when you type "ipconfig /all" on this other computer?
