G'day,

I've setup a Virtual Machine with windows XP + sp2 from a Windows 2003
machine (server administrator configured it) and copied the VM to the Vista
32 sp1 machine to use.

When I open up the XPsp2 VM on a Vista 32 computer (user) I had to do the
following.
1. Set the IP address manually on the VM (didn't like to set it from DHCP).
2. Enabled public sharing on the VM XP system.  Vista could see the VM PC
and access public folders.
3. Could ping the local Vista PC ip address.
4. Could ping the local DHCP server/router.
5. Failed to ping any internet addresses. Eg. ping www.microsoft.com
6. With the Vista and XP firewalls off, failed to ping internet addresses.
7. With the vista and XP Firewalls off, failed to ping any other IPAddresses
in our WAN (VPN IPSEC).
8. Vista doesn't display icons for all our newtwork resources (Some VPN/WAN
discovery problem), but happily connects to those resources via a lmhost
file. So I know I have connectivity.
9. After enabling Vista internet sharing and disabling firewalls, failed to
ping internet addresses from the VM.
10. Couldn't find out how to install a loopback provider on Vista (not sure
if this is a windows XP thing).

So I have a VM that really needs to access other resources from the WAN
(like out SQL Server 2005on Windows 2003) as the VM is being used for
application installation testing, but the lack of network connectivity is
blocking me.
What do I need to do to get this work?

Let me get this straight first. You want the vm to look like another
computer on your LAN. Is that correct?

   If that is the case, it should have worked with the default settings.
(ie NIC set to link to the physical NIC in the host and the vm set to get
its network config automatically). You do not need to install a loopback
adapter. (Incidentally, you install a Microsoft loopback adapter on the
Vista host from Control Panel | Add hardware).

   If you have network connectivity to the local LAN you should be able to
get your network config from the DHCP server on the LAN. If you can't, it
could be a problem with the NIC driver on the Vista host. Check to see it
there is a newer version available from the NIC manufacturer.

   Even if DHCP doesn't work, everything should be OK with a manual config.
Have you set the netmask, gateway and DNS address to the same values as
those on the host?

   If you are in doubt, post an ipconfig listing from both host and guest.

   I have pretty much an identical setup running here (Windows XP SP3 and
Server 2003 SP2 guests on Vista SP1 Business host running VPC 2007)  and the
guests behave just like the host. They get their network config from DHCP
and can access any site which the host can access.

Bill,
Thanks for the solution.  In the VM XP I used cmd.exe and Ipconfig to solve
the problem.  I didn't have the "default gateway" correct, so after a manual
change, then re-enabling the connection everything worked.

Bill,
Secondly to answer your intial question, no I don't want the VM to simulate
another computer, its just a shared VM on a server that other remote offices
use to test with.  Our software developers just copy down a "starting point"
VM from the server and make adjustments according.  If there is a 'problem',
they copy down the original and start over.  

Finaly, the fact you could give me a response and solution in a few hours is
absolutely amazing.  Thanks very much. If your ever down in Australia, give
me a call and I'll buy you a beer!

Well in that case, when you come up to Brisbane or the Gold Coast, look me
up at www.jenasysdesign.com.au and we will honor that promise.

Alas, the poor Rabbitohs!  Only one win.  After last year I thought they
were on their way again.
