TW -
So it seems to definitely be due to Zone Alarm 5.....
If you decide you want to stick with ZA, instead of XP's firewall, can you get hold of an earlier version?
I still use the last 4.5 version, & have never had any problems like this with it.
Or, there are various other free firewalls...See this post for a list:

Oh, & I've split the thread from the "
NTL & P2P" thread by the way, as it now seems to be a ZA problem, rather than the usual NTL/P2P problem.
