Jos,

In addtition, I looked up port 27015. It is being used usually for a game called Half-Life - which I never played or installed in my machine. The other port number changes with every reboot.

Thanks!

Dennis

>The two established connections are to your own computer as identified by "localhost". The localhost means "this computer" and has IP 127.0.0.1. You will also notice that the two established connections loop back to each other via the port numbers. I suspect this is probably ok but you could investigate further to see what process / program specifically is using these ports. See also - http://en.wikipedia.org/wiki/Localhost
