When you use the OfficeScan client uninstallation program to remove the OfficeScan client program from a computer, the program automatically notifies the server. When the server receives this notification, it removes the OfficeScan client icon in the client tree to show that the client does not exist anymore.

However, if you use other methods to remove the OfficeScan client, such as reformatting the computer hard drive or deleting the OfficeScan client files manually, OfficeScan will not be aware of the removal and it will display the OfficeScan client as inactive. If a user unloads or disables the OfficeScan client for an extended period of time, the server also displays the OfficeScan client as inactive.

To have the client tree display active clients only, configure OfficeScan to automatically remove inactive clients from the client tree.
