Re: DHCP from Router to SBS Server

If you are using a single NIC configuration you can use the DHCP on the router *IF* your router supports forwarding DNS to a computer on the LAN side. In other words, if your router supports forwarding DNS to the SBS computer, then you should be OK. If it doesn't then you may be in trouble. This can be hard to find out--the documentation on the consumer grade routers I've used at home was worthless in that regard (5 different models from assorted vendors). I had to experiment, and I eventually settled on using m0n0wall. But if it does work, run CEICW and turn off DHCP, and set the DNS addresses in CEICW to your ISP's DNS addresses -- not the router!
I have not run into problems running m0n0wall as NAT/router/firewall, because it has a configuration screen specifically for DNS forwarding that seems to work. Quoting from that screen: "If the DNS forwarder is enabled, the DHCP service (if enabled) will automatically serve the LAN IP address as a DNS server to DHCP clients so they will use the forwarder." and then it lets you set up the SBS host, domain and IP address as target. Unfortunately I could not find such a screen on Linksys, Netgear, D-Link or Airlink routers.

I have been running a SBS 2003 box with 10 clients for over a year. I was
using the router to do my DHCP but was told that the SBS should be doing the
DHCP. I switched to using the SBS for DHCP and could not get the clients to
see the server. The DHCP service appeared to turn itself off on the server.
So I gave up and went back to using the router and all hell broke lose now.
I'm running in a domain environment. All the clients can not talk to the
server unless I use static IPs and reboot the all the clients every morning.
All the clients take a very long time shutdown and reboot. The internet is
very slow on the clients. The server appears to do something every night
that cause the clients to communication with the clients.
Please help,
