Re: Multiple server problems - HELP!

Hi Jack,

Configure the external nic (the one currently disabled) manually.

IP Address (Static) 192.168.1.2
Subnet: 255.255.255.0
Default Gateway: 192.168.1.1 (your router lan IP)
DNS: 192.168.16.2

Connect this nic to the lan side of your router.

Run the Change Server IP wizard, located in Server Management | Standard
Management | Internet and Email. Change the IP to 192.168.16.2

You want to end up with an internal nic configuration like this:

IP Address (Static) 192.168.16.2
Subnet 255.255.255.0
Default Gateway: <blank>
DNS: 192.168.16.2

Connect this nic to a hub/switch - all of your wokstations will be connected
here as well, (not to the router).

Run the Connect to the Internet wizard from the same page as the Change
Server IP wizard (above). Specify which nic is your internal nic, and which
is your external nic. When asked for DNS forwarder addresses, you can enter
your ISP's DNS server addy(s) if you know them, or leave them blank if you
don't.

The net result of the above is that you should end up with a corrected DNS,
DHCP, and WINS configuration on the SBS server.

Connect a workstation to the same hub/switch as the SBS internal nic, and
change the networking configuration to a full DHCP client. Run ipconfig
/release ipconfig/renew, or restart the workstation to get the correct
settings from the SBS dhcp server.

That should correct most of your issues, if not all. You may have some
devices (printers, possibly) with static IPs that you'll have to attend to.
I'm not sure what device you're using for wireless, but you'll likely need
to move it to the internal hub/switch as well, and configure it as an Access
Point, so the SBS DHCP can pass through it.
