Hi Larry,

Sure, this can be done easily.

Put two nics in the SBS. Give the 'external' nic an IP in the same subnet as the router, and use a different subnet for the 'internal' or 'lan' nic.

Example:

Router IP 192.168.0.1 (DHCP server 192.168.0.x, subnet 255.255.255.0)

SBS external nic - IP 192.168.0.100, same subnet as above. The IP can be any unused IP, preferably static, and you may want or need to make a reservation for it in the router DHCP configuration.

SBS internal nic - IP 192.168.16.2, subnet 255.255.255.0 (these are SBS defaults).
You can run DHCP on the SBS - it will automatically be set up for you as part of the SBS installation and configuration process (wizards).

You now have the option of connecting a switch or hub to the SBS internal nic to connect workstations, and/or remotely accessing the SBS via it's external nic (for remote administration, configuration, etc.). Your SBS will have outbound internet connectivity, and you may elect to port forward from the router for incoming access. The 'Connect to the Internet' Wizard will configure RRAS (basic firewall), or ISA, to route between the internal and external nics, and prevent the SBS DHCP server from shutting down.


You will need to replug your workstation either to the existing router
or the SBS internal connection (directly by crossover cable or via a
hub/switch). You will need to switch the workstation to domain mode
while connected to SBS, and may need other configuration differences.
It may be worth dual-booting two separate XP installations on the same
machine to minimise disturbances if you do it often. I have a particular
need to do this as my wife may well use my usual workstation, and I want
it to boot up by default in a usable condition. I don't feel like
explaining over the phone how to switch from DHCP to fixed address, or
worse, if I've forgotten to change something back.

VMWare is certainly a useful way to go, but there's always the nagging
doubt as to whether the emulated hardware is behaving exactly as real-
world hardware does in a normal network. When you have subtle network
problems, it's nice to be able to reproduce the physical topology.

The point often missed these days is that computer hardware that is
no longer state-of-the-art is nearly free, and perfectly OK for test
purposes. I occasionally have four computers running, only one of
which I bought new.
