Reference Servers<br />

8-14<br />

One of the ways the <strong>OfficeScan</strong> client determines which of the firewall profiles or Web<br />

Reputation Policies to use is by checking its connection status with the <strong>OfficeScan</strong><br />

server. If an internal client (or a client within the corporate network) cannot connect to<br />

the server, the client status becomes offline. The client then applies a firewall profile or<br />

Web reputation policy intended for external clients. Reference servers address this issue.<br />

A client that loses connection with the <strong>OfficeScan</strong> server will try connecting to<br />

reference servers. If the client successfully establishes connection with a reference<br />

server, it applies the firewall profile or Web reputation policy for internal clients.<br />

Take note of the following:<br />

• Assign computers with server capabilities, such as a Web server, SQL server, or FTP<br />

server, as reference servers. You can specify a maximum of 32 reference servers.<br />

• Clients connect to the first reference server on the reference server list. If<br />

connection cannot be established, the client tries connecting to the next server on<br />

the list.<br />

• <strong>OfficeScan</strong> clients only use reference servers when determining the firewall profile<br />

or the Web reputation policy to use. Reference servers do not manage clients or<br />

deploy updates and client settings. The <strong>OfficeScan</strong> server performs these tasks.<br />

• A client cannot send logs to reference servers or use them as update sources<br />

To manage the reference server list:<br />
