Network active

[Jude]

Hi all

Does anyone have any idea why my network would sometimes be showing 
as mounted, even though I don't have a network set up?

I noticed that when I did permissions repair that the directory 
./private/var/at/jobs and ./private/var/at/spool have been changed, 
and a search of recent changes shows a lot of activity in the 
invisible 'private' area as well as some stuff like davlocks being 
run.

Also, what is an AECore-pipedmessage?

cheers
Jude
