I have Windows Vista Business as my host OS and Windows XP Pro as the guest.
I connect to the Internet from the Vista through a USB mini-modem, and I want
to share this Internet Connection to XP. Is it possible? How could I do that?

Thank you

Sure, just set the networking adapter option in the virtual machine
settings to "Shared Networking (NAT).

Thank you, Robert.

But I tried this, and it did not work. Nothing else must be configured in
the guest OS? Is it just open Internet Explorer and type an URL?

Thank you again.

Just the default networking settings in XP should be enough.

Do you get any kind of error when starting the virtual machine?

No error message is displayed anytime.

Sorry about my question, because I am not good at networking, but when I
type "ipconfig" under the prompt, my local area network do not have a default
gateway. Is that right? I thought I should set a new connection or somethig,
must not I?

Thank you

It should have a gateway.

It should look pretty much like this for the Shared Networking (NAT)
setting:

(192.168.1.1 is my router)

Do you have a firewall that might be blocking communication from and
to the VM?

I am not using any firewall but the Windows firewall. I tried to disable the
guest Windows firewall, but no success yet.

I repaired my Local connection in the guest OS and now I got a gateway, but
it seems it wasnt the problem at all. My settings looks like yours, except
for the DNS server:

Is there something else I could try?

Thank you

The only thing I can think of is maybe a host NIC driver issue -- you
might try and see if there is an update for it.

Other than that, I don't know, but maybe someone else here might...

The first thing I would do is uninstall the Nortel software from the vm.

If you can't get it working with Shared Networking (NAT), install a
Microsoft Loopback Adapter in the host and use ICS on the host to share its
connection to the vm.

Actually I had installed the Nortel Contivity VPN Client on my host OS also,
and before reading your post I tried to uninstal this software on my host
only, and did not change anything in the guest... and that worked! I could
even connect to my business VPN through Contivity Client under my VM.

Somehow this software was disturbing shared networking between host and
guest. Now everything is working fine!

Thank you everybody!
