I also have a problem where I am disconnected occasionally when either finding sources or during downloads.

I am on XP pro and event log reports a 'tcpip' warning and describes something about the number pf connections in the stack has been reached. (event 4226) I get the event exactly at the time I am disconnected.

LW pro 4.9.30 / xp pro / 1gb ram / 2.6 P4
I have broadband 2mb connection via adsl usb wired modem (BT).
Norton internet security is on fully and xp firewall is on.

Anyone know of a way to stop this from happening? All help gratefully received.
