tcpip.sys Warning

Hello:

I am running my PC with a D-Link Wireless N Adapter (e-PCI) to a D-Link Wireless N Router connected to Cable Modem from Comcast. Things were fine for a long while. Then I started getting some drops in Internet Connection generally around night time.

I will sometimes either be in the middle of google video/Youtube, or just go away for a while, then I notice that my Windows Live Messnger loses connection and cannot reestablish connection, browser can't browse anything, I can't access my router from my wireless PC, the only thing that still works is reading hotmail through Outlook Express, all this time the Wireless Link still show as Connected.

At first I thought it was the power cycle the cable modem solution, after that didn't help, it seems that if I restart my PC, the connection started working again. Just logging off and logging back on won't work, I have to actually restart the PC.

Anti-Virus and Spyware scans turn up nothing, and I can't see anything strange in Task Manager, msconfig, and the hijackthis logs. Then looking at Event viewer, it seems that the Warning 4226 on tcpip.sys seemed to be generated around the time that I loses the connections....

TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.

Could this have been what's causing the connection drops? Too many con-current connecitons at once while Windows XP Pro allows only 10? It doesn't happen every night (I use my PC on a nightly basis), but just once in a while, and granted my PC isn't too slow, but this get annoying after a while. I did some research and it seems that this may be caused if I am running some P2P applications in the background, the thing is whenever I get the drops in connection, I am usually not running my bt apps, the only peer-to-peer-like app running during those times is usually Messenger. It just seems strange that reading mail through OE is the only thing that still works while just about everything else fails.

Any suggestions of why this is happening and solutions is appreciated.

Thanks,

Shohoku79, SWAG, can't tell you just why, but have a couple of guesses. First is 'temp' files. Those fill as you do things and if they're not cleared each time they're used, can significantly slow or even stop things.
Next, a common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated. It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner (free @: http://www.ccleaner.com/) can get rid of it (not to worry, it gets rebuilt EMPTY on the next boot.). Dunno if they're the deal or not, but treating them won't hurt anything.
HTH.
