ANET is the correct command to use to set the zone that you wish the PC to
reside in. The exact format of the command is:
ANET USE MLIDname Z zonename
where MLIDname is the name of the MLID you are using, and zonename is the zone
you wish to reside in. Executing this command also stores these values in the
NET.CFG file, keeping them across restarts of the machine. For more
information on this command, check page 132 of the "AppleShare PC User's
Guide."
