When running the Configure E-Mail and Internet Connection wizard in SBS 2003, you had the option to run DHCP services on the SBS server, or leave it on the router within the network.  There was no guidance one way or another, it was a choice you had to make to complete the wizard.

The guidance is that you should run DHCP on the server.  Why?

  1. Microsoft builds, and has been building a really high quality DHCP server built into Windows Server since Windows NT 4.  Why not get one of the highest quality DHCP servers on the market for your network?
  2. The SBS team can ensure your DHCP server is set up correctly on SBS, making sure there are no duplicate IP addresses, and that the exclusion range is set up correctly for the server’s IP address
  3. If you feel comfortable in the DHCP management UI, you can set up reservations to make sure the same clients get the same IP address.  This is handy for printers, or other things on your network that may act like servers, but you don’t want to manage the static IP address
  4. If you’re logging in remotely, you can see which clients are online by which ones have IP addresses in the DHCP management console.  You can also see the clients IP address right in the console, so it makes it easy to find clients on the network, especially if you are remote.
