About once a week I find that I cannot access the network at my work
from my home Win7 machine. ping fails, and tracert does not manage a
single hop. The address is 130.216.11.141.

I have found that the problem is resolved by restarting the computer.
This is a bit annoying, and I'd like to get to the bottom of it. Any
suggestions?

One reason I don't like to restart is that I have to close Mozilla
Firefox and lose all the open tabs, which raises another question. On
earlier versions of Firefox it gave you the option of saving the tabs,
to be reopened when Firefox is started again. The current version
(8.0.1) doesn't do this. Can I select this behaviour somehow?

A. Your open tabs are automatically saved, but not automatically restored.

To restore your tabs at the start of the next session, use
"History >> Restore Previous Session"


B. If you want your tabs to be *automatically* restored every time you
start Firefox, then in Firefox go to:
"Tools >> Options >> General"
and change the setting
"When Firefox starts"
to
"Show my windows and tabs from last time".

I don't know what you mean. Leaving it open when?

I should add that when this IP address is inaccessible I can still
browse the rest of the web normally.

Check the logs of your router for it doing any "intrusion detection"
carryon. I find with many parallel SSH transfers my old one would often
block it and call it an attack.

I had a look in Event Viewer (the only place I know to look for router
messages) but I didn't see anything. Maybe I need to look somewhere else.

More info: I use Cisco VPN client to use my work computer from home
(Remote Desktop). I have now determined that when this error condition
exists, it is being connected to the host via VPN that makes the host
network unreachable (Remote Desktop doesn't connect, ping fails, tracert
doesn't get to my DSL modem). If I disconnect from VPN then I can ping
the host again. In other words, the VPN client is somehow causing the
host IP to be blocked for other processes. Does this make sense?

That is normal behavious for most VPN connections - it is a security
risk otherwise - in that your local internet connection and computer
could provide a path to your work (VPN connection).

You can workaround it, IIRC, but I'd ask your work first, as it's likely
to be against their security policy.

I get around that by running the VPN on a virtual PC.
