Internet expertise

I have a dell Windows XP machine. I am having trouble
connecting to the internet. If the machine is set for a
dynamic IP, the machine won't grab one. If a static IP is
input with the DNS numbers, I can ping the router, i can
ping the DNS servers, I can ping yahoo's ip address, but
when i try to ping www.yahoo.com, it can't resolve. When
i use IE and try to connect to www.yahoo.com i get "page
cannot be displayed", if i put in the ip i get "page
cannot be displayed". I removed the nic and reinstalled,
i tried a different nic, still no help. I can't open the
web interface for the router, nothing in ie works but, i
can ping ip addressed but not names. The DNS #'s all work
on another machine. I tested the cable, cable is fine,
tried a different port on the switch, still no help.
Driving myself crazy, hoping someone has a help hint.

Thanks in advance

John,

This sounds very much like a DNS hijack and / or Winsock / LSP corruption.

How current is your virus protection? Try these free online virus scans:
<http://www.bitdefender.com/scan/license.php>
<http://www.pandasoftware.com/activescan/com/activescan_principal.htm>
<http://security.symantec.com/ssc/home.asp>
<http://housecall.trendmicro.com/housecall/start_corp.asp>

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 variants.

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.
3) Have your HJT log interpreted by experts at one or more of the following
forums (and post it here):
<http://forums.net-integration.net/>
<http://www.spywareinfo.com/forums/>
<http://forums.tomcoyote.org/>
<http://www.wilderssecurity.com/>

Finally, try LSP-Fix and / or WinsockXPFIx after spyware checks are finished.

And John, please don't contribute to the spread 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.
