Can you get to the Web? If so, try going to "www.whatismyip.com" with a

tried this, but it sound feasible.

True. But the rest of the post said:
"Is there a simple command that can get this info into a program
running on the guest?"
That's a bit more complicated I'd think.

I, personally, haven't done it, but there are "stripper" programs that
can run under scripting control that will 'strip' all the text off a web
page. You run this and look for the page:
www.whatismyip.com/automation/n09230945.asp
This page is what is showing your IP address. whatismyip.com tells this
to you if you look in your browser and "Show page source". Look for the
instructions for using this page.

But I did want some trick to give me this info programmatically
because I need my virtual W2003 server to discover the IP regularly.
I run this guest in Virtual Server 24/7 to act as my VPN gateway from
outside into my internal network.
For a couple of years I have used an ISP who has given me a fixed
address, but now I have to switch to a different provider, which only
supplies DHCP addresses.
So I need some way to know what is the current external address my
router uses since that is the address I need to point my VPN
connection at.
The plan was to have the W2003 server regularly check the external
address and then publish it in a webpage on a private homepage at the
ISP where I can look it up if the connection fails.
Maybe there is a better solution?

Have you looked into using a dyndns service? It seems like you're doing
all this so that you can know (externally) what IP address a (virtual)
machine has been given by it's ISP. The router will probably have a tab
in it's configuration menus for hitting a dyndns server. This is a
service that each time your router negotiates a new lease, it will ping
the dyndns service and the IP address will be recorded. The upshot of
this is that you get a URL that you can use to access the machine.
Something like http://somedyndnsserviceorother.org/myaccountid123 and
that resolves to your IP.
