"The SBS and all its domain member clients must shown *only* the SBS LAN
IP address under DNS servers"

This is wrong. You obviously put the SBS box in there first but having
other external DNS IPs allows the clients to resolve and still use the
Internet if the server is down. Also if there is a second domain
controller that would be listed.

Note that if you use the 2 NIC solution then you will not be able to get
to any DNS servers of course - but that way of setting up SBS is
completely wrong as far as I'm concerned in most installs. Thank
goodness MS has seen sense and scrapped this idea with SBS 2008.
