Sorry to start a new thread, but search didn't yield me any help. I have a windows xp home laptop, running a penium-m 1.8g, 2gig ddr2, 80gig, 6800nvidia. Using Avast Antivirus, zonealarm firewall, and adaware personal. The system is fully updated/patched from microsoft. The system seems clean of all spyware/adware and no trojan/virus can be found with the latest updates.

Recently my web browser has lost the ability to load pages (both IE, and firefox). The blackout will last for 30-60 seconds. The connection then returns. During the blackout, I retain connection to IRC, and voice communication programs. No internet games drop either. I can /ping any site, including the one that currently will not load in my web browser. Downloads from websites are not affected.

If anyone has any suggestions, please let me know. For the moment, I have disabled zonealarm firewall and turned on the basic windows firewall. This has netted me no change.

Look in your Zone Alarm logs and see if it shows rejecting anything connecting in them.
You didn't say how you were connected - whether dialup or broadband and on direct connection to the modem or with a router, and if so is it wireless?

If it is wireless, make sure you do not have a portable phone (or any other wireless device) on the 2.4mhz band anywhere near the router or the computer.

If you can't determine any cause, go to Windows Live Onecare Free Scan.
That will check registry issues among other things.
It will say "Get a free PC safety scan"
http://safety.live.com/site/en-us/default.htm

Make sure you click "Full Service Scan" in the middle of the page and
not the "Try It Now Free" on the right side.

Allow it to download Active X components.
Choose "Complete Scan" in the window that opens
Click "Next"
Do not click on anything else that offers you a free trial or to sign up if you live in the US.

Allow it to scan - it may take quite a while, maybe two hours or so depending on how big your hard drive is and how fragmented your registry and drive are.

Take a minute to look at the info in the link below:

The system is wired to a WAP/Router. The other 2 systems in the house which are wireless do not have this issue. The laptop (system with problems) has the same issue wired or wireless. (diabled wireless adapter)
I ran the microsoft live cleanup/scan found a few small issues, but none of them corrected my port 80 issue. I cleared the API cache as well, with no luck.

Any other suggestions are welcome.

Have you done a hijack this log? You might find something interesting in that... If your running mirc there's a possibility you have something associated with it. However, for now make sure all programs that are associated with the internet is closed (mirc aim msn) don't cancel components, just software, have zone alarm running though. Whenever you lose connection to your computer, go to start>run>cmd(enter) Then type in

Netstat

Netstat -an

netstat -vb

Post up what these three guys come up with. Try to do this frequently to notice any changes.
