Disabling Novell Send Message with Zen

Hi all,

I work at a public school, and the children have discoverd Novell
sendmessage (before I did). Someone suggested exporting a registry file
that has send message disabled, and then adding a line to the students
login script that initializes those changes. However, other people have
told me that Zenworks is the best way to go. The students machines are
locked down with deep freeze, so the changes will have to be made every
time a user logs in.

I am posting here because I do not know alot about zenworks, and I need a
push in the right direction. For instance, I made the registry file with
the correct settings, can I use it in Zenworks? Also, do I make an
application object, or a user policy?

Any help is appreciated, thanks.
