Win XP & Browser Problem

Here's one that's been roasting our chestnuts for two weeks now. Newer XP machine, virus & malware free*. We can ping, update apps, IM etc all day long. But to surf with either IE or FF we loose conectivity after ~a 15 minute instance. Reboot brings back browser function for another ~15 min's. If we exit the browser before we loose connectivity, we can open it back up and continue surfing... aggragate time does not cause loss of connectivity.

Thoughts or ideas? No, linux/mac isn't an option.

I would download Process Explorer....keep it up and see if you can get any insight into what is happening about time connectivity goes wonky.

Other tools that may help give clue:

What about doing an extended ping? leave it running while pushing the data into a text file.

ping www.google.com -t > c:\test.txt

When your internet cuts out see if the ping test cuts out as well. This will give you a hint if it is post 80 taking a crap or maybe your internet connection is hooped. Also you might find the latency shoots through the roof, again pointing at a bad internet connection.

I don't believe it's a wonky connection. This is one rig on a LAN. All the other drops have been working fine. But I'll give it a try. Thanks.

can you ping it from another machine when it goes ape on you?

Try to set up an SMB share from it and see if you can upload/download.

Then try to FTP to something, upload a file, then download to another directory. CRC check that against the original (just being thorough as hell)

If all of that works, but no web browsing, then something is probably locking up port 80 or 8080.

Yeah, I say disable the built-in software firewall and just use the one in your router. Also check the system & apps log in the EventViewer and see if there's anything acting up.

MSN and other IM's work on some degree of caching. By keeping a constant ping going you can completely rule out your internet connection BARRING any problems with your firewall blocking port 80 (sometimes severe collisions can cause the same problem if you are using an internal network).

Ideally, find a site using a different port and test against it. This rules out the port blocking problem

or....shutdown all firewalls possible and see if you still have the same problem.
