Many businesses use Norton AntiVirus servers to keep the company's servers and client computers virus free. In order to keep the virus definitions updated, the Live-Update is used to schedule virus definitions download to the main NAV server, which in turn, updates the client computers. From my experience, some integrators seem to be having difficulties with the LiveUpdate configuration on a network protected by ISA Server, so I decided to write this article. The LiveUpdate feature requires both HTTP and FTP access to Symantec's web site. In order to configure ISA to allow the main server to download definition updates, use the following instructions:   Open the ISA management console. Expand the Server -> Policy Elements -> Client Address sets in the ISA tree. Create a Client address set named "NAV Server". Enter the IP address of the server on which the Norton AntiVirus Server is installed. If the NAV server is installed on the ISA Server itself (such as in the case of SBS 2000), make sure that the IP address specified is the internal IP address of the server (the private ISA server IP address). Expand the Access Policy object, and create a new rule in Protocol Rules. This rule should allow the specified client address set which was created in step 3 to access FTP and HTTP sites. Install Symantec Norton Anti-Virus for Servers, include all the components recommended by Symantec. Open the "Norton Antivirus Corporate Edition" program. To schedule a daily download of new virus definitions, open the "Symantec System Center" console, expend the "System Hierarch", and right click the Norton Server group (by default named "Norton Antivirus 1"). Select All Tasks -> Norton AntiVirus -> Virus Definition Manager... Don't forget to additionally configure how Client computer retrieve the definition update. The recommended way is to Update virus definitions from parent server. That way, the new virus definitions will only be downloaded by the NAV server, and not by the client computer.
