I'm running MS Virtual PC on fully patched XP with W2003 as a guest. I
start a ping from guest to host and host to guest, and it will run for
about 10-20 minutes without issue. At some point it just stops/pauses
and I just get "Request timed out" on both sides. From either side I
can ping another system on the network with no problem - they just
don't ping each other anymore.

Now get this: If I open a browser window to any website on the host,
all of a sudden both environments continue their pings again. I can
open a browser to an internet site in the guest, but that doesn't
"unclog" the connection between the host and guest.

I don't see anything in event logs, nothing weird in pfirewall.log
which I turned on just for this. I've temporarily turned off Windows
Firewall for both environments, though I don't like that state. I'm
running Norton Antivirus 2006 but that doesn't monitor network
traffic. I'm not running any other a/v, port scanning, or firewalls
except an external hardware firewall.

Can someone lead me to any diagnostics I can use to figure out why the
comms are dropping here?

Thanks.

I would have you look at the Power Management settings for thst NIC. By
default, they are set to "Allow the Device to Turn Off" to Save Power, even
on a desktop.

You nailed it !!!! Thank you so much!

My discovery of your solution was delayed, my Usenet feed for these
forums didn't catch your post. It pays to not trust the medium and
look elsewhere to see if someone else's feed did any better.
