Port 80 shut down?

I don't know if this belongs here since I know it's not a problem in the network itself, it's only on my computer. I've prettymuch isolated it to a problem with XP or some part of it.

I've been having this problem ever since I reinstalled XP almost a year ago and it's really starting to get to me now, as its occuring more often than ever. I have to reboot to fix it. Sometimes it'll go a day being fine, sometimes I have to reboot every 5 minutes.

Whenever I get a lot of connections coming in/going out on my computer, the HTTP port stops working. Everything else functions fine, I just can't connect to anything on port 80. I have to reboot the computer to fix the problem, then port 80 will be working immediately. Right now I'm accessing this site through a secure proxy on port 443.

The strange thing about this is, it happens when I'm using uTorrent or another P2P program (for LEGAL use, most often downloading amateur-recorded tapes of live concerts) and browsing the net at the same time. 99% of my traffic would be coming in/out through another port. It seems as though if it is some kind of security thing that it would restrict access on the P2P application's port, but the P2P programs continue to function normally. I can also ping/traceroute to whoever/wherever I want and it'll get there at a normal speed.

I know the problem isn't with my network, since while my port 80 is down on this computer I can hop on any other computer in the house and do whatever I want. Plus if it was in the cabling, NIC, ISR, or any of that, wouldn't nothing work?

Also I'm pretty sure it's related... if I view a webpage with a lot of connections to different hosts, only a portion of the content will load. Then when I try to navigate away from the page my whole internet will go down for about 5 minutes before I can do anything again.

Does anyone have any idea about this?

    You could try to manually set the MTU size on your computer.
    If you are on DSL you want to set it to 1492, if you are on cable then it should be at 1500, which is the default

    I'm on cable, so if the default is 1500 and it should be at 1500, then doing that wouldn't make a difference would it?

    Nope wouldn't be worth while at all.

    ok well thanks anyway. Do you have any other ideas?

    Nope. Normally that sort of problem is almost entirely an issue on the router. For whatever reason though your nic seems to be getting over loaded which is just bizarre because your nic can support more connections then your WAN port on your router. So typically if you are being bombed your router should drop off before your PC will.

    If I were in your shoes I'd. Check for new drivers for your nic and make sure all your other windows patches and everything else is up-to-date. I'd also do a complete virus/spy ware scan to make sure you don't have something else that is generating extra traffic.

    yeah I figured that too. And it's not my whole connection that's being dropped, only the HTTP traffic. I already updated my NIC driver and it didn't make a difference. There's no malware and as far as I know everything's up to date.

    You could try and rule out software/hardware by booting up in a live linux distro and viewing some of those web pages that are causing problems and seeing if it persists.

    One other thing I just thought of. If you are using IE try firefox. Could just be an issue with IE crashing.

    Some other things to check. Clear your browser cache and delete all cookies. Then change the ammount of cached files from the 3 gigs or so that it's probably storing now to like 150mb.

    I've had SuSE Linux for a while but I can't create a new partition to install it on. I tried Partition Magic and it wont create it. I don't know if thats somethign to do with it being an OEM computer.

    I've tried Firefox, no difference.

    My cache is set to 1GB. Wouldn't I want to increase it?

    No don't install linux. Get a live distro. A live distro is a version of linux that you don't need to install it'll run directly off the cd and not install anything on your computer. Ubuntu and Knoppix are two that I use frequently and both work very well.

    No you don't want a bigger internet cache it clogs your harddrive and can get corrupted. Plus with a high speed connection there are diminishing returns when you start to cache large quantities on your harddrive, the bigger the cache the more it has to do a comparison of new vs old etc...
