The Updates dialog window, located in the section Server Options, serves to define update parameters for ESET Remote Administrator Server. The window is divided into two sections. The upper one lists Server Updates options, the one below is dedicated to update mirror parameters. Since the version 2.0, ESET Remote Administrator Server offers the feature Mirror which creates a local update server for client workstations.




There follows a description of all elements and features:


· Update server - this is ESET’s update server. It is recommended to leave the predefined value Autoselect
· Update interval - specifies the maximum interval between two consequent checks for the availability of new update files
· Update user name - user name of the user used by ESET Remote Administrator to authenticate to update server(s)
· Update password - password belonging to the given user name


To launch an update task providing downloading of all most recent components for ESET Remote Administrator, click Update now. Updates may contain important components or functionality; therefore it is vitally important to make sure that updates work properly and automatically. In the case of problems with update, select the Clear Update Cache option to flush the folder with temporary update files. The Mirror Downloaded PCU option allows you to activate program components mirroring (PCU - Program Component Upgrade). To set up PCU mirroring go to Advanced > Edit Advanced Settings and configure settings in ESET Remote Administrator > ERA Server > Setup > Mirror (or Mirror for NOD32 version 2).
The configuration of mirror in ESET Remote Administrator Server is the same as in the versions ESET NOD32 Antivirus Business Edition and ESET Smart Security Business Edition. There follows a description of important mirror elements:


· Create update mirror – activates the feature Mirror. If this option is disabled, no update copies are created.
· Create mirror for the selected program components - allows user to specify language variants and types of program components that will be created in Mirror.
· Populate mirror with selected program component updates only on demand - if enabled, PCUs are not automatically mirrored. If you want to enable PCU mirroring, select the Mirror downloaded PCU option in Tools > Server Options > Updates
· Mirror folder – local or network directory dedicated to store update files.
· Enable update distribution via HTTP – serves to enable accessing updates using an internal HTTP server.
· HTTP server port – defines the port, on which the ESET Remote Administrator Server will provide update services.
· HTTP server authentication - defines the method of authentication used for accessing update files. The following options are available: NONE, Basic, NTLM. Select Basic to use the base64 encoding with basic authentication. The option NTLM provides encoding using a safe encoding method. For authentication, users created on the workstation sharing update files are used.
· Create update mirror for NOD32 version 2 products - create update mirror for older ESET products (version 2). The updates are located in "nod32v2" subfolder of the mirror folder.


Click Default in the section below to restore predefined values for all features in this window.


NOTE: If the HTTP server method is in use, we recommended a maximum of 400 clients updating from one mirror. In large networks with more clients, we recommend balancing mirror updates among more ERA (or ESS/EAV) mirror servers. If the mirror needs to be centralized on a single server, we recommend using another type of HTTP server, such as Apache. ERA also supports additional authentication methods (e.g., on Apache Web Server the .htaccess method is used).


The administrator must insert the product license key for a purchased product and enter the username and password to enable the Mirror feature in ERAS. If the administrator uses a license key, username and password for ESET NOD32 Antivirus Business Edition, then later upgrades to ESET Smart Security Business Edition, the original license key, username and password must be replaced as well.


NOTE: ESET NOD32 Antivirus clients can also be updated using a ESET Smart Security license, but not vice versa.
