What method should I choose in ESET Remote Administrator for my clients to download virus signature updates?
On a network managed by ESET Remote Administrator, your client computers can be configured to download their virus signature updates in one of four ways. The purpose of this article is to help you decide which method is best for you and direct you to Knowledgebase instructions for setting up each configuration.
Method 1: Standard HTTP Mirror
The most widely used method is to use a Mirror server that downloads your Virus signature update from ESET's servers only once and allows your clients to pull the update from a local machine via HTTP. This method prevents excess traffic across your LAN and works regardless of whether your individual client computers have Internet connections and open ports. ESET recommends this configuration for most small- and medium-sized business networks.
Method 2: Shared Network Mirror folder
A variation on the Mirror server configuration is the Shared folder as your Mirror. You can use network sharing, rather than HTTP, to pull the virus signature update from a single centralized location on your server. Your server is still only downloading the update once. Though ESET recommends Method 1, you may wish to use a Shared folder if you have unusual internal filtering on your network that is blocking HTTP traffic between your server and your clients.
Method 3: Download directly from ESET's Internet update servers
You can configure your clients (via Policy Manager) to each download the Virus signature update directly from ESET's servers over the Internet. You may wish to select this method if your local server is unreliable or has regular periods of downtime, since your clients will be able to update directly whether or not your server is up. Also, your clients will get each Virus signature update as soon as ESET releases it, rather than than waiting for scheduled network updates.
You may wish to choose Methods 1 or 2 instead of this method if you wish to have an intermediary step between the ESET servers (Internet) and your client computers. If each is downloading from the Internet independently as in this method, you will have no such option. Method 3 requires that each client has a reliable medium-to-high bandwidth Internet connection, with the correct ports open and no web blocking software preventing your ESET security product from downloading.
Method 4: Microsoft IIS Mirror
As in Method 1, you can create a Mirror server and configure clients to access the Mirror server for updates and then set up Microsoft Internet Information Services (IIS) to act as the mirror server. You may wish to do this if your network is already IIS-enabled and you and your staff are familiar with IIS. Also, if your business is a large enterprise with more clients than can be feasibly supported via HTTP-based mirroring, this method may be best for you.
