Lost Internet Capability -- How to Recover?

[saberman]

I have lost internet connectivity but with a catch.

Reconstruction of events (as near as I can recall):
Installed Vista Ultimate with SP1
Installed Office 2007 Ultimate with SP1
Setup Outlook for Mail and News Groups. Working fine.

Installed Virtual PC
Create two Virtual Machines (Windows XP Pro SP3)

Host and both virtual machines were able to access the internet.

Everything seemed fine for a couple of days. Virtual machines and host were
communicating fine.

Then the host lost internet connectivity. When I tried to renew the
connection with ipconfig it said it could not find the file. Yet the guest
vritual machines still had internet access. I could stop them, stop Virtual
PC, start Virtual PC and start the virtual machines and they still had
internect connectivity.

I could not find a way to re-establish internet connectivity on the host.

Any idea what could have caused this and how to recover the host's
connectivity without restarting it?

What file is this that the system couldn't find?

What file is this that the system couldn't find?

It happened again. This time I let the machine go to sleep mode while one
of the VM's was open. When I woke it up the next day the host did not have
any connectivity but the VM did. I was able to do a tracert from the VM to
a couple of web sites. I could shutdown the VM and then start it and it
still had connectivity.

Here's a log of the ipconfig tries on the host (Connection 2 is the a
hardwired connection to the router. The other connection is not hooked
up.):

The 169.254 IP means that the O/S couldn't get an IP from the DHCP
server on the router in a timely manner. So it assigned the 169 IP to
the network interface card. The machine will be able to access other
machines on your Local Area Network-LAN, but the machine will not be
able to access the Internet, since it's not using a valid IP on the router.

You can try ipconfig /release and ipconfig /renew to make the machine
try to obtain a DHCP IP from the router, when you wake it up.

I'll try the release/renew combination next time it loses connectivity.
However, shouldn't the ipconfig /renew been sufficient? More importantly,
why is it losing connectivity in the first place?

No, you have to do the release first. And if it doesn't release, then
you might have to issue the Netsh command to reset the TCP stack.

As far as Vista not working with your router, Vista doesn't play well
with some routers. Also there may be a firmware update for the router
concerning Vista that may not be applied.

Thanks -- I'll try that the next time I lose connectivity.

BTW, Outlook 2007 is also a little flaking as a News reader. I can't see
the posting that I sent and you responded to. However, Agent running under
Windows XP SP3 (on a different physical machine) downloaded the posting
fine. But that's for another news group.
