People,
Every so often, my Firewall (Norton Personal Firewall) pops up an Internet Access Control window during web surfing that advises I block a high risk remote system which is attempting to access my machine.
I always opt for the block; never giving it much thought...& then continue on.
Today, out of curiosity, I went to Internet Access Control in NPF to see what these remote systems were.
They were various Inbound
TCP, UDP, IMCP &
NetBIOS Services...utilizing any number of different ports.
What are these services; & how does this all work?
Thanks very much,
