McAfee MANAGEMENT EDITION 2.5 Administrator's Manual page 143

For scheduled updates, the Update Manager attempts to contact the member
machines that it wants to update. If the Update Manager receives a reply from
the Management Agent on the target machine, the update takes place and is
recorded in the Update Manager's database. If the member machines fail to
reply, the Update Manager tries again several times and at regular intervals,
as you have specified earlier.
For updates on request, a program (the Update Requester) runs as the machine
logs on, and communicates with the Update Manager. If the update is not due
to be issued yet, the user continues working, uninterrupted. Normally, the
Update Manager prompts the user to accept the update. The user accepts, and
the machine is updated with a copy of the new anti-virus software. This may
take a few minutes, so the user can choose to postpone the update. At later
logins, the user will not be allowed to postpone further, and is forced to take
the update.
Follow these steps to install to member machines using Batch Install:
1. On the Management Console's main menu, click Tools, and then choose
Options.
The Options page appears, with the Remote Installation page showing.
2. Click the Batch Install tab.
The Batch Install page appears
3. Select Update from login script or Scheduled update(s).
4. Set the date and time for which the updates may be applied.
