You must manage your networks for the critical but infrequent situation when too many clients simultaneously request a full set of virus and spyware definitions from the management server or from a Group Update Provider. This situation can occur if the management server encounters an error or runs out of disk space, so that the download and update of the definitions on the client then fails. This situation can also occur if the management server does not download a definitions package and a client then requests this specific delta. In either case, the client then must request a package with a full set of definitions from either the management server or from the Group Update Provider.
To help prevent overloads on your network, the management server provides the following features:
A notification when the management server receives a specified number of requests for a full set of definitions within a specified period of time.
You set the conditions for this notification based on what constitutes an overload for your environment. To configure the notification, add a Network load: requests for virus and spyware full definitions notification condition.
The ability to let clients get deltas for virus and spyware definitions from a LiveUpdate server if the management server can provide only a full set. In a LiveUpdate Settings policy, click Advanced Settings > Download smaller client installation packages from a LiveUpdate server.
The ability to block clients from downloading a full set of virus and spyware definitions from the management server.
If you receive a notification of a network overload, you can block any further downloads of full packages from the management server. You cannot, however, stop any downloads that are already in progress. Configure this option by clicking Admin > Servers > server_name > Edit the server properties > Full Definitions Download > Prevent clients from downloading full definition packages.
