Loss of internet connection?

Is there anything (virus related) that might hose up a system's
internet connection - so much so that you can't ping the outside world
from a command prompt? Its not just IE thats messed up.

I have two systems in the office with this symptom. A week ago there
was only one, it was loaded with spyware.

Then this week another PC started showing symptoms of something trying
to hijack the web browser -but it too has lost its internet access so
the browser (internet exploerer) fails to display.

Its driving me nuts trying to track this one down.

Also, in IE, nothing happens when I click Tools | Internet Options on
the second pc; I get no Options dialog box - nothing.

The first PC, when I r-click NW Neighborhood, the system prompts me
for a Office 2000 CD ???

Any ideas? I've just never seen an internet connections get hosed
like this - could it be remenents of a virus? Virus detection
software isn't finding anything.

Thanks,

Mike
 
I see that you say it was loaded with spyware, but then say that your
AV finds nothing, Have you tried an anti trojan program such as Spybot
or Adaware.

Who mentioned a web server? Its a simple peer-to-peer, no file or
print sharing - no pc can see any other on the network. The network
is there simply to provide internet access to each pc in the
organization.

everyone there is a separate entity - there is no need to share. Its
a shared office space.

Too many to id it from your description, however given what's been
common lately, I'd check for the qhosts and coolwebsearch trojans,
and also run spybot, and adaware.

Note, for spybot and adaware, be sure to download the latest updates,
after you install the program, but before scanning your system.

Then use a known clean boot disk, and run a full av scan.

Also, make http://www.claymania.com/safe-hex.html mandatory reading
for everyone in your office, with a comprehension test after<G>.
