2. From the Clients tab, select all clients that currently connect to OLD_SERVER.
3. Right-click the selected clients, and select New Task → Configuration Task.

4. In the Configuration for Clients dialog box, click Create…

5. In the Configuration Editor, navigate to ESET Smart Security, ESET NOD32 Antivirus → ESET Kernel → Setup → Remote administration.

6. Change the Server address to NEW_SERVER (no http://), or use the IP address of NEW_SERVER, in the form xxx.xxx.xx.x (again no http://).

8. In the Update server parameter, enter the IP address of NEW_SERVER (http://xxx.xxx.x.x:xxxx).

Configuring an ESET client solution as a local Mirror Server

ESET Smart Security Business Edition and ESET NOD32 Antivirus Business Edition client solutions can be configured to store copies of virus signature update files, much like a standard Mirror server. These virus signature files can then be used to update other workstations that are running ESET Smart Security or ESET NOD32 Antivirus. A version 4.x or version 3.0 ESET client solution that is configured as a Mirror server cannot be used to update ESET NOD32 Antivirus 2.7 clients.

To configure an ESET client solution as a Mirror server, perform the following steps:

Open the main program window by clicking the ESET icon  next to your system clock or by clicking Start → All Programs → ESET → ESET Smart Security or ESET NOD32 Antivirus.
 

Press the F5 key to display the Advanced Setup window. From the Advanced Setup tree, click Update and enter the license information supplied by ESET in the Username and Password fields. Make sure the Update server: drop-down is set to Choose Automatically.

From this point you can configure the Mirror to provide updates via an internal HTTP server, or via a shared network folder. To provide updates via an internal HTTP server, perform the following steps directly below (to provide updates via a shared network folder, click here):

1. Select the Create update mirror and Provide update files via internal HTTP server check boxes.
    
2. In the Folder to store mirrored files: field, enter the directory path to the folder that will contain the update files. Do not enter values in the Username and Password fields.
    
3. If you wish to use a port other than the default port (2221), click the Advanced setup button and enter the value in the Server port: check box (the default value is recommended unless you have other applications communicating on this port).

To configure the Mirror to provide updates via a shared network folder, perform the steps directly below after clicking the Setup… button in step 5.

1. Created a shared folder on a local or network device. This folder must be readable by all users running ESET software, and writeable by the local SYSTEM account (If the shared folder is located on another computer in the network, it is necessary to specify authentication for accessing that computer. Click here for additional information).
    
2. Select the Create update mirror check box. Do not select the Provide update files via internal HTTP server check box.
    
3. Enter the name of the shared folder (created in step 1) in the format \\UNC\PATH.

If the Windows 7 HomeGroup feature is having difficulty connecting to other users, your ESET Smart Security Perasonal firewall may be blocking the connection. To allow HomeGroup connectivity, you will need to create rules on every computer protected by the ESET Smart Security firewall on the network.

1. Open the main program window by clicking the ESET icon  next to the system clock or by clicking Start → All Programs → ESET → ESET Smart Security.
2. If you see Display: Standard mode in the lower left corner, switch to Advanced mode by clicking Change… or by pressing CTRL + M on your keyboard.

4. Attempt to connect to other computers in your HomeGroup. Your ESET Personal firewall will prompt you to allow or deny each connection that is not defined by an existing rule. To create the rules you need, select the Remember action (create rule) option in the dialog window.

.

When you have created the rules you need, set the Personal firewall to Automatic mode with exceptions: While in the Advanced mode display, click Setup → Personal firewall (see steps 1-3) and then click Switch to automatic filtering mode with exceptions

The Personal firewall will now function as it would in Automatic mode, while maintaining the specific exceptions (rules) that you defined for problematic applications in Interactive mode. For advanced troubleshooting information on blocked connections in the Personal firewall, click here.
