Joe, try setting the starting address for DCHP on your router at 100 and limit the number of addresses to what you need for the laptops/notebooks + 1 for guest system. Then you can use static IPs for all the other systems on the network as long as you keep the addresses below 100. I use this method at my home (6 systems) and at work (145 systems).
Also set your DNS addresses at the systems WIN2003 as 1st, Router as Second, 3rd as Internet provider's DNS and 4th a Public DNS Server. When your mobile users are in the office they will get their IP from the router, their DNS Info from the WIN 2003 box if it is up, the Router next, etc. When the mobile users are out of the office if can find d DCHP server it may or may no act as a DNS server, but it does matter because you have give their systems a place to find a DNS server. Even you are in a company that issues IP's but won't pass or share DNS data to limit internet access you users should be able to get to and use the internet.

Internet access is via cable modem connected through a router to all machines. I need to have the machines use the DNS server in the 2003 box while that box is functional. If the 2003 box is down, the router should handle the DNS. My current router's DHCP server has no setting to control the Preferred or Alternate DNS server values it distributes. Does someone know of a router with a built in DHCP server that does support those settings? I expect there would be a way to setup a Linux box to do the job but I would prefer avoiding adding any equipment with rotating parts. Another possibility would be to have two DHCP servers (router and 2003) with non overlapping ranges. Is there a way to ensure that the 2003 one would always win when it is running? Might a switch between the router and the rest of the LAN add enough delay to have 2003 get there first?
