I have 3 PC's on our network that suddenly lost their internet connection. I
can ping in and out and can display a numeric IP address but it will not
display a regular web site. I know it hase something to do with the address
translation but all of that seems to be running fine. Possibly a worm. Any
help/suggestions would be much appreciated.
Jeff,
Can you ping by name successfully? Or is that a problem too?
How current is your virus protection? Try one or more of these free online
virus scans:

Now check for, and learn to defend against, additional carriers of infection.
First, download LSP-Fix and WinsockXPFIx from <
http://www.cexx.org/lspfix.htm>,
and CWShredder from <
http://www.majorgeeks.com/download4086.html>. All are
free.
Next, close all Internet Explorer and Outlook windows, then run CWShredder.
Have it fix all.
Now check for, and remove, spyware. Get HijackThis
<
http://www.majorgeeks.com/download.php?det=3155> and Spybot S&D
<
http://www.safer-networking.org/index.php?page=download>. Both free.
1) Install and run Spybot. First update it ("Search for updates"), then run a
scan ("Check for problems"). Trust Spybot, and make all recommended deletions.
2) Install and run HijackThis. Do NOT make any changes immediately. Save the
HJT Log. <

If removal of any spyware affects your ability to access the internet (some
spyware builds itself into the network software, and its removal may damage your
network), run LSP-Fix and / or WinsockXPFIx.
And Jeff, please don't contribute to the spread and success of email address
mining viruses. Learn to munge your email address properly, to keep yourself a
bit safer when posting to open forums. Protect yourself and the rest of the
internet - never post your address unmunged.
