To perform initial configuration tasks, you must log in to Horizon Administrator. You access Horizon Administrator by using a secure (SSL) connection.


  • Verify that Horizon Connection Server is installed on a dedicated computer.
  • Verify that you are using a Web browser supported by Horizon Administrator. For Horizon Administrator requirements, see the View Installation document.


  1. Open your Web browser and enter the following URL, where server is the host name of the Connection Server instance.
    Note: You can use the IP address if you have to access a Connection Server instance when the host name is not resolvable. However, the host that you contact will not match the SSL certificate that is configured for the Connection Server instance, resulting in blocked access or access with reduced security.

    Your access to Horizon Administrator depends on the type of certificate that is configured on the Connection Server computer.

    If you open your Web browser on the Connection Server host, use to connect, not https://localhost. This method improves security by avoiding potential DNS attacks on the localhost resolution.

    Option Description
    You configured a certificate signed by a CA for View Connection Server. When you first connect, your Web browser displays Horizon Administrator.
    The default, self-signed certificate supplied with View Connection Server is configured. When you first connect, your Web browser might display a page warning that the security certificate associated with the address is not issued by a trusted certificate authority.

    Click Ignore to continue using the current SSL certificate.

  2. Log in as a user with credentials to access the View Administrators account.
    You specify the View Administrators account when you install a standalone Connection Server instance or the first Connection Server instance in a replicated group. The View Administrators account can be the local Administrators group (BUILTIN\Administrators) on the Connection Server computer or a domain user or group account.


After you log in to Horizon Administrator, you can use View Configuration > Administrators to change the list of users and groups that have the View Administrators role.
