Hi:
I would like to have a small training on how these applications work. I had
a very difficult time when I was trying to use them and gave up about a
month ago. I've been meaning to post to the list and publicly thank Graham
for all the help he gave me while I was trying to recover a lost system. He
was very supportive and had great tools that helped me bring the lab back
online.

Yes, that's correct. We are currently just trying to manage clients from
the Ghost Console, which uses multicast, and we haven't yet attempted to do
anything with the GhostCast server. Ultimately, we would like to use the
GhostCast server, however.
In any case, it's helpful to know that directed broadcast probably won't be
an option because we would need it enabled in multiple subnets across
campus.
Thanks, Ken and Kevin, for your responses.
