This setup is for taking a laptop to client site to demo Outlook/Exchange
functionality

Laptop host is running XP Pro, guest is Windows Server 2003 VM. I have
loopback adapter that is fixed to 192.169.0.1 and my NIC IP is 192.10.0.116.
ICS is enabled on the NIC and I can connect out from guest and connect into
guest from host.

However, I cannot ping guest from anywhere else on the external network
presumably because it's on a different subnet. Is there something I can do
on the host to enable me to connect to the guest from machines other than
the host?

tx

Not really. ICS is just a cut-down version of NAT, and that is how NAT
works. It is a one-way address translation. Machines on the private side can
see out, but machines on the public side cannot see in.

Bill, Thanks - is there a Virtual Server configuration like the bridged
networking that VMServer uses ?

Just set the NIC in the guest to point to the physical NIC on the
host.
Then it will get the same capabilities as the host has. It will act as
a second NIC but sharing the same TP cable.

Bo, Thanks - if the guest and the host have the same IP address and I remote
to that IP, which do I hit? Did I misunderstand your advice?

They will not have the same IP address. Each NIC has its own hardware MAC
address and its own IP address, just like multiple machines on the same LAN.

Sorry if I'm being dim but what does "point the NIC on the guest to the
physical NIC on the host" mean?

1) Inside the VPC2007 console, select the thumbnail image that
represents your guest machine.

2) Click the Settings button with the guest shut down

3) Click the networking item in the list to the left

4) For Adapter 1 to the right drop down the combobox

5) In this box there should be at least 4 items:
Not Connected
Local only
<The name of your network card in the host>
Shared networking (NAT)

6) Of these you select the name of your host NIC

7) Click the OK button and start the guest machine

Now VirtualPC will use the Virtual Machine Network Service on the host
to create a new "logical" network card using the hardware of the host
network card but with a different MAC address.
This new NIC (different from the host logical NIC) will appear on your
external network and when the operating system starts it will have the
IP address you define inside the guest operating system.

If you have set the guest NIC for "Automatically get IP address" then
it will ask for a DHCP server on the *external* network and get its
address from that server. It will be a different IP address from the
one your host has because these are different network cards (different
MAC addresses).
Now you have two compters on the external network (host and guest) and
they can communicate exactly the same so they will be able both to go
to the Internet and talk to each other.

Notice that the presence of an external network router with a DHCP
server is needed for this. But that is what most people have these
days (the ADSL/DSL modem/router box usually has a DHCP server so you
can connect multiple PC:s to the same internet connection).
If you connect the Internet directly to your PC then you need to get a
hardware router to put in between the Internet and your host PC.
