Uh-Oh. Gone a bit off the rails here. You do understand the difference
between a client and a server application don't you? GRC would only see port
110 open if you were running a server. Your client connects to port 110 on a
remote server and does not open port 110 on your machine.

What about some instructions for the NT & XP users? What do they do?

This is of course complete bollocks. A VPN connection could be there quite
legitimately for connection to a corporate network. The fact that there are
two of everything has probably got more to do with multiple network
connectors than hackers!

Or you have the Blaster worm (minus windows 95 and 98)

I thought I'd try this for a laugh. I was shocked. It created a 70Mb text
file which brought Notepad to its knees and contained exactly the same thing
as I could see in REGEDIT. I fail to understand how exporting the registry
to a text file will actually show anyhting that can't be seen in REGEDIT.
Please explain.

Phew! Nothing there! Just a bunch of undechiperable crap.

My head is in a spin. I can download a port scanner from zdnet but I musn't
go online before I do a port scan using a port scanner I can download from
zdnet but I cant go online......

Explain please?
