My Gigabit lan freeze after prolong use in Win XP Pro?

[picard]

Why does my Gigabit lan connection freeze in window XP after few hours of use? I have Asus P4C800 deluxe mother board. The board lan is 3COM 3C940 model. I have to reboot window XP when it freeze causing loss of internet connection. I have window firewall and Micro trend antivirus installed on system. Micro Trend firewall is enabled at medium level. I cleaned PC RJ45 port with air blower.

I tried to renew IP address, Flush it, reboot cable modem, reboot router without success in restoring internet connection. The only way is to reboot window XP it self. I tried to unplug/replug ethernet cable from the PC but it doesn't have any effect. Could the lan card problem is due to my Micro Trend firewall?

I am testing the lan in window 2003 to replicate the same problem.

sometimes I have that problem in my laptop. Could never find out why it happens or when it happens, but to solve it, I disable the adapter and enable it again

ok thanks for the tip paul. I test my built in lan adapter on window 2003 and it works fine without freezing. I wonder if Window XP is causing freezing. By the way, my pc also runs emule.

I disable multicasting on my router. Would it affect the lan adapter ?

oh man, emule can cause your network to go down fast if you don't have limits set for your upload and download connections, actually that applies to any p2p network apps out there, torrents too

you need to cap your upload, download doesn't really require a cap, but get a feel of it so your network doesn't become so congested that the connection will just give out

this is an issue xp sp2 where they've limited the number of half open connections from unlimited to just 10, this is a big blow to all p2p apps, you might even have a similar error message in your system event logs

there's some hacks for it...but no real way of getting around it without risking your connection's stability

oh ok. I didn't know emule can cause connection to crash. I have to check the cap limit on both upload and download. thanks for the tip fatTony. I think this is the main cause for my crash connection.

Ok. I change the connection of emule to 10 but my NIC still freeze after 2hrs. It never happened like this before I install Microtrend antivirus 2007. could the antivirus causing this???

Can someone help me? I need emule to get important data.
