TCP/IP problems

[Jeff]

I am working on a Windows XP Home PC that is having some
TCP/IP problems. It uses a dial-up connection to get to
the internet. The modem dials and connects fine, and if I
do an ipconfig, I can see that the computer is pulling the
proper IP, Subnet, and Gateway addresses. However, I
cannot ping any address. Any ideas what the problems may
be? I have turned the firewall off, and no help. Any
suggestions are appreciated. Thanks.

Interesting,,,,

I am dealing with a PC that exibits the same issues when connecting through a high speed ( cable modem ) connection. It belongs to a neighbor and while trying to diagnose the problem, I connected it to my home network and am unable to connect here as well.
Did you attempt to reset the IP stack?

 

[Jeff]

No I have not. I will probably try to attempt that in the
morning. My first thought was that it was a modem issue,
but it is negotiating with the dial-up servers and it is
connecting and pulling an address.....so it has to be
something with either Windows or the TCP/IP. I know the
PC had tons of spyware on it, which I have hopefully
finally removed. My guess is that is the root cause to
the problem. I have never reset the IP stack in XP
before, so I may have to do some research on that in the
morning and give that a shot.

Many ISP's have started blocking ICMP ports at their routers due to misuse.
It's often used in ddos attacks by changing the packet size and bombarding
IP addresses with it.
This could also be the problem you might check with them if everything else
seems normal.
Can you ping the loopback address, if so I'd venture to guess there is
nothing wrong with the stack.

I reset the IP stack, and no help. I can ping my own
address....and the 127.0.0.1 address, but nothing else.
Hooked another pc up, and it works fine. Any more ideas??
