VisualAge

script ang got the following error message:

error: host not found

Host not found? What doeas it mean?

Cananyone help me to interpretate this error message?

I had this message on MacOs X 10.2 then I upgraded to 10.2.2 and it
worked !!

It was late in the night so I didn't try to log in the admin site, I
just watched the initial screen, then I shut down and went to sleep.

Later, I launched an updater (in 10.2-autoconf-patch.pkg format) I
downloaded from the Apple site and BAM !  It didn't work any longer ! 
The message popped up again !

AAaargh!!!

Please, help me!
 Thanks, anyhow
Bye
