Subject: Re: Tech Tip: This is how You Disable Dcom & close Down Port 135

Nicely worded Anteaus

I will have to disagree on what you wrote referring to the end result having
a useless box that will only be able to play cards...solitaire...LoL .

For example, my pc has only 1 listening service port running and that 1
service is not any of the default listening ports. Hhmm...

So...what functionality does mi computer have then? ....plenty..not only
play solitaire..surf the net...e-mail....play multiplayer games like
Fear..and all sorts of FPS games...hmm so far lots of functionality.

Importantly doing something like this in a workstation work environment
might not be desirable.

It is up to the individual home user to learn what the risks are, by leaving
services on the default setttings. Also learn how their OS functions.
