cannot ping web address

[karlo]

Hello,

I have Windows XP networked in a peer to peer via TCP/IP. It is also
an ICS client. Until recently, all was fine. But, now, it cannot
connect to the Internet. It can still see other computers on the
network and access shared drives. It can ping a another computer's IP
address. It can ping an Internet IP address, like x.x.x.x. But it
cannot ping a web address, like "my.yahoo.com".

I have another XP ICS client that has no problems.

please help.

thanks,
Karlo

Hi!
It lloks like there is some problem with the DNS
settings in your client computer.DNS or the domain name
system converts the IP address to domain names.If instead
of typing in the doamin name; you type in the IP address
of a website in the browser; does it open? The solution to
this should be; go into TCP/IP properties and instead of
auto DNS settings, select preferred DNS server and then
type in the IP address of your ICS host.Your internet
should work fine now..
Thanks and Reagard;
Ambarish.

Hello Ambarish

Hello,

Solved the problem. It had to do with McAfee Personal Firewall, which
came with VirusScan 6.0. I shutdown the Firewall, totally disabling
it, necessitating its reconfiguration to restart using its
configuration wizard. After reconfiguring and restarting, everything
works. I can browse the web and check email.

Odd thing is, I always made sure the NIC's McAfee Firewall Network
Filter was unchecked, before the problem started, while the problem
persisted, and after soloing the problem, so that the Firewall would
not be active on that NIC. Yet it still seemed to be blocking traffic.
I was able to ping internet IP addresses, but I could not ping URL's.

I would appreciate hearing what people think is the root cause.

Before doing the above, I did try what you suggested.

system converts the IP address to domain names.If instead
of typing in the doamin name; you type in the IP address
of a website in the browser; does it open?

No it did not. But, I was able to ping the internet IP address from
Command Prompt. I was not able to ping the associated URL.

The solution to this should be; go into TCP/IP properties and instead of
auto DNS settings, select preferred DNS server and then
type in the IP address of your ICS host.Your internet
should work fine now..

Did that. It didn't work.

What gave me the clue was

http://support.microsoft.com/default.aspx?scid=kb;en-us;316522

which I found in a search for "cannot ping URL " at Microsoft's
knowledge Base . Before doing what they suggested, I first tried the
above.

I have the exact same problem as Karlo only the client is
a Win 2000 laptop. I tried the solution suggested by
ambarish and put the preferred DNS server IP address into
the TCP/IP DNS configuration on the Win 2000 client and
it still will not connect to the internet. Any other
suggestions would be appreciated. Thanks, Scott
