Henry,

Why don't the instructions just say that? That's rhetorical, right? I gave up
trying to understand Microsoft years ago.

Your observed background network activity could be one of several things. Maybe
your browsers communicating with the master browser. Maybe services being
broadcast by each server. Maybe ARP traffic. NetBIOS is a very chatty
protocol. Hopefully nothing to be alarmed about, but you might want to keep an
eye on ZA anyway.

Get Port Explorer (free) from
<http://www.diamondcs.com.au/portexplorer/index.php?page=home> to show you what
network connections your computer is actually opening, and what processes are
opening them.
And Process Explorer (free) from
<http://www.sysinternals.com/ntw2k/freeware/procexp.shtml>. Provides way more
information than Task Manager.

Glad you got it solved. Maybe we both learned a bit. Thanks for the feedback.

Paranoia comes from experience - and is not necessarily a bad thing.
