HTTP fails at least once a day
I have two computers connected to my linksys router. A Win7 (wireless) and my XP SP3 (wired). The Win7 never has any problems. About once a day, I lose http connectivity. I can ping sites, but not use HTTP to get html pages. There are no other errors. When it occurs, suddenly, sites are unavailable (the Win7 laptop is always OK). Also, I have four drives connected via a router; three of them (usb drives) are still accessible when this occurs, but my other, a MyBookWorldEdition mirrored drive, is not. Only rebooting fixes it reliably. Sometimes, powering down the router (or the cable modem) helps but that is rare. Happens with IE8, FireFox, and Chrome. When it occurs, I cannot access the router via HTTP, either. IPCONFIG/ALL is the same before and after. Any help is appreciated.RON1 person needs an answerI do too

Hi, ·What is the service pack installed on XP computer? 1. Disable any third-party security software installed on your computer. And check the results. If the issue does not persist, it might be caused because of the settings. You may have to change the settings Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks. 2. Check the behavior by booting the computer in clean boot state. You may refer the below link on how to configure Windows XP to start in a "clean boot" state:http://support.microsoft.com/kb/310353If the issue does not persist you may continue with step 2 from the above link.Make sure you reset the computer to normal mode after the installation completes. Refer the section “Steps to configure Windows to use a Normal startup state” Regards:Samhrutha G S - Microsoft Support.Visit our Microsoft Answers Feedback Forum and let us know what you think.

SP3, service pack. I've tried disabling anti-virus software; nothing helps. This all started out of the blue one day about 9 months ago. There are no events in the event log relevant to this (as far as I can tell) RON

Look, I know it's nearly impossible to diagnose the cause of this from a distance. BUT, I am hoping someone will point me in the right direction. What entity in the OS is getting corrupted? Where would I look? The registry? TCP/IP stack? And how? Shutting off anti-virus apps that I have had running for years seems like just poking around in the dark.

I did find something in the Event viewer. TCP/IP errors: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts. RON
