A strange win98 networking problem

Hi there,

I have a windows 98 machine infected by a virus called something like Zafi.
I successfully cleaned it. However, after that networking doesn't work
properly.

The win98 machine is one of the LAN that is connected to the Internet using
boardband. After cleaning, the machine is working fine inside the LAN. That
is, it can see/access all the other machines in the LAN, transfer files,
etc., but it cannot access the Internet. All the settings are correct.
What's strange is that:

(1) It can ping the ISP's website (www.bigpond.com), but nothing else! Even
though I can ping the website, I cannot view the site using IE (other
machines can!).

(2) It cannot ping/access other sites in the Internet, but tracert command
showed that the IP packets have already reached beyond the gateway of the
ISP.

(3) Even though it's working fine inside the LAN, it cannot connect to the
terminal server, but it can ping/access the server and transfer files with
the server.

What problem could it be??? Is there any tool that I can use to detect the
problem? I think netmon might (might not?) help, but I cannot find a proper
version for win98.

By the way, TCP/IP is the only protocol installed. I even uninstalled and
reinstalled the TCP/IP part, but didn't help.

Any idea please???

Thanks in advance!!

TCP/IP isnt the problem in this case since you are able to
ping pong your gateway and other websites. Your IE is
messed up ( I think..) Are you able to connect to other
applications that use internet? like MSN messenger or
yahoo messenger. Are you able to download files from FTP
servers? There is no DNS problem either since you are able
to ping the website using its address.
try reinstalling IE.

Hi Nimit,

Sorry I forgot to mention it, but no other TCP/IP applications work - cannot
FTP, cannot TELNET, etc...

The hosts (WINNT\System32\Drivers\etc\hosts) file is a list of IP addresses
and names which serves the same function as DNS. A Windows client will
check its local hosts file before sending a query to its DNS server. Just a
guess, but some Trojans/Worms populate your hosts file with phony IP
addresses. Your ping problems might be the result of sending packets to the
wrong address per the hosts file.
