Hi
As the connection attempt is coming from NTL I can only assume that they
are checking you're 'still there'. Some ISPs check periodically if the
user is still connected (normally for dial-up users) but maybe they do
it on HSI as well, I don't know I'm on Telewest Blueyonder. I've not
heard anyone reporting any connection attempts from NTL on port 139
though. If it is a 'heartbeat' connection attempt you could always add
the gateway IP address(es) to your local zone as well. Have a look at
this description form the Zonelabs site:
