It would appear that you have two NICs in the SBS (there's not much
point to Premium otherwise). You also have the same network address
(192.168.1.) on both NICs, which is the cause of the problem. They must
be different, since among other things the SBS is a router, and cannot
determine which NIC is connected to the default gateway.
If you are using VPN, or are likely to do so, then the 192.168.1.
network is not a good choice, because VPN is also based on routing, and
it's not unusual for clients to use that network by default.
So connect to the Internet router and change its IP address to
something like 192.168.37.2 (use a single PC/laptop plugged into it if
you can't reach it from anywhere else, and of course you will lose
contact when the network address changes.) Set the SBS external NIC to
something else in that network, presumably the .1 address, and you
should be back in business. You'll probably need to run the CEICW again.
If you do want to change the internal network address, SBS has a Change
IP Address wizard, which will do it all for you. You'll need to reboot
the LAN clients afterwards.
And going back to the beginning, you don't need to worry about the
router anyway. The SBS DHCP server will operate on the LAN network
only, the external IP address will be fixed, and the router can run a
DHCP server without affecting the SBS. Just make sure the router pool
does not include the SBS external NIC address. This is a useful way to
work, as visitors' laptops can be plugged directly into the router and
get DHCP information, and they will have an Internet connection
without being able to reach the LAN.
For future reference, Microsoft no longer maintains this newsgroup, and
queries should now be posted to:

and you'll need a Hotmail or Live email address to post.
