How do I configure ESET clients to access the Mirror server in ESET Remote Administrator? (4.x)

After you have created your Mirror server, you must configure client workstations to access it for updates. There are two methods for configuring client workstations to access the Mirror server.

A new version has been released

Version 6 of ESET Remote Administrator (ERA) and ESET business products were released in North America December 11th, 2014, and globally February 25th, 2015. This article applies to version 5.x and earlier ESET business products. For information about what's new in the latest version and how to upgrade, see the following article:

Method 1: Create and push an .xml configuration file from the ESET Remote Administrator (ERA) to client workstations.


Method 2: Manually configure each client workstation to access the Mirror server.

If you only have 4 or 5 client workstations which will be accessing the Mirror server for updates, you may prefer this method.


When using the HTTP server method, we recommend a maximum of 400 client workstations updating from one mirror. On large networks with more than 400 client workstations, we recommend balancing mirror updates among additional ESET Smart Security, ESET NOD32 Antivirus, or ESET Remote Administrator mirror servers. If the mirror needs to be centralized on a single server, we recommend using another type of HTTP server, such as Apache or IIS.
