Maintaining internet connectivity

Posted: 01-19-2009, 09:06 PM
On my desktop computer running Window XP pro with SP2, I can connect with the
internet after a cold boot, but after 5 or 10 minutes, or 5 or 6 websites,
internet connectivity is lost.
This occurs whether I connect through a router or directly to the cable
modem
Even after internet connectivity is lost, the computer is still connected
to the isp. I can ping other sites, connect with a vpn, send and receive
e-mail. Thus, Thus, it does not appear to be a problem related to my
desktop's network adapter card or driver (thought I have tried deleting and
re-installing them).
The cable modem and ethernet cable have been replacet, to no avail.
This occurs with either browser, Internet Explorer or Mozilla Firefox,
i.e., it does not seem to be a browser-specific problem
This does not occur when I use one of two laptops - they connect either
directly or wirelessly through the same router and establish and maintain
internet connectivity.
I have listed both browsers as exceptions in Windows Firewall, tried
turning off all anit-virus and anti-spyware programs and anything else I can
think of that might be interfering.
The only other link in the system that I can think of is the operating
system. I have not been able to find anything that reveals the problem or
corrects it.

I would appreciate your input!

is windows firewall the only firewall you use, I would hope you only have
one, but have heard of people using more than one.

Windows firewall is the only one. I forgot to mention earlier that I had SP3
on the computer but took it off. It had been interfering with the wireless
connectivity on my laptops so I had taken it off of them and then removed it
from the desktop to see if that would help. It didn't.

This used to be a problem with zonealarm and your internet connection timing
out due to it not being added to the trusted zone. not sure about windows
firewall.
I use KIS for a firewall. Kaspersky Internet Security
