The server polling feature addresses the issue of unreachable OfficeScan agents not receiving timely notifications about component updates and changes to agent settings. This feature is independent of the heartbeat feature.
With the server polling feature:
OfficeScan agents automatically initiate connection with the OfficeScan server at regular intervals. When the server detects that polling took place, it treats the agent as "Unreachable/Online".
OfficeScan agents connect to one or several of their update sources to download any updated components and apply new agent settings. If the OfficeScan server or an Update Agent is the primary update source, agents obtain both components and new settings. If the source is not the OfficeScan server or Update Agent, agents only obtain the updated components and then connect to the OfficeScan server or Update Agent to obtain the new settings.
