Connection options

To access the proxy server setup options for a given update profile, click Update in the Advanced setup tree (F5) and then click Profiles > Updates > Connection options.

Proxy server

Click the Proxy mode drop-down menu and select one of the three following options:

  • Do not use proxy server
  • Connection through a proxy server
  • Use global proxy server settings

Select Use global proxy server settings to use the proxy server configuration options already specified in the Tools > Proxy server branch of the Advanced setup tree.

Select Do not use proxy server to specify that no proxy server will be used to update ESET Endpoint Security.

Connection through a proxy server option should be selected if:

  • A different proxy server than the one defined in Tools  > Proxy server is used to update ESET Endpoint Security. In this configuration, information for the new proxy should be specified under Proxy server address, communication Port (3128 by default), and Username and Password for the proxy server if required.
  • Proxy server settings are not set globally, but ESET Endpoint Security will connect to a proxy server for updates.
  • Your computer is connected to the Internet via a proxy server. Settings are taken from the browser during program installation, but if they are changed (for example, if you change your ISP), please make sure the proxy settings listed in this window are correct. Otherwise the program will not be able to connect to update servers.

The default setting for the proxy server is Use global proxy server settings.

Use direct connection if proxy is not available – Proxy will be bypassed during update if it is unreachable.

Windows shares

When updating from a local server with a version of the Windows NT operating system, authentication for each network connection is required by default.

To configure such an account, select from the Connect to LAN as drop-down menu:

  • System account (default),
  • Current user,
  • Specified user.

Select System account (default) to use the system account for authentication. Normally, no authentication process takes place if there is no authentication data supplied in the main update setup section.

To ensure that the program authenticates using a currently logged-in user account, select Current user. The drawback of this solution is that the program is not able to connect to the update server if no user is currently logged in.

Select Specified user if you want the program to use a specific user account for authentication. Use this method when the default system account connection fails. Please be aware that the specified user account must have access to the update files directory on the local server. Otherwise the program will not be able to establish a connection and download updates.

Username and Password settings are optional.


When either Current user or Specified user is selected, an error may occur when changing the identity of the program to the desired user. We recommend entering the LAN authentication data in the main update setup section. In this update setup section, the authentication data should be entered as follows: domain_name\user (if it is a workgroup, enter workgroup_name\name) and password. When updating from the HTTP version of the local server, no authentication is required.

Select Disconnect from server after update to force a disconnection if a connection to the server remains active even after updates have been downloaded.
