After logging in to a server, you can connect to the remote desktops and published applications that you are authorized to use.

If your administrator has allowed it, you can configure the certificate checking mode for the TLS/SSL certificate presented by Connection Server. To determine which mode to use, see Setting the Certificate Checking Mode in Horizon Client.

If you want to use an account configured with unauthenticated access to launch published applications, see Connect to Published Applications Using Unauthenticated Access for information.


Obtain the following information from your Horizon administrator:

  • Instructions about whether to turn on a VPN (virtual private network) connection.

  • Server name to use for connecting to the server.

  • If the port is not 443, the port number to use for connecting to the server.

  • Credentials for logging in, such as an Active Directory user name and password, RSA SecurID user name and passcode, RADIUS authentication user name and passcode, or smart card personal identification number (PIN).

  • Domain name for logging in.


  1. If a VPN connection is required, turn on the VPN.
  2. Either open a terminal window and enter vmware-view or search the applications for VMware Horizon Client, and double-click the icon.
  3. If you are prompted for RSA SecurID credentials or RADIUS authentication credentials, enter the user name and passcode and click OK.
  4. If you are prompted for a user name and password, supply Active Directory credentials.
    1. Type the user name and password of a user who is entitled to use at least one desktop or application pool.

      If the Domain drop-down menu is disabled, you must type the user name as domain\username or username@domain.

    2. (Optional) Select a domain value from the Domain drop-down menu.
    3. Click OK.
  5. If the desktop security indicator turns red and a warning message appears, respond to the prompt.
  6. (Optional) To configure display settings for a remote desktop, right-click the remote desktop icon and select Settings.



    Select a display protocol

    If a Horizon administrator has allowed it, use the Connect Via drop-down menu to select the display protocol.

    Select a display layout

    Use the Display drop-down menu to select a window size or to use multiple monitors.

  7. (Optional) To mark the remote desktop or published application as a favorite, right-click the remote desktop or published application icon and select Mark as Favorite from the context menu that appears.

    A star icon appears in the upper-right corner of the remote desktop or published application name. The next time you log in, you can click the Show Favorites button to find this application or desktop quickly.

  8. Double-click a remote desktop or application to connect.

    If you are connecting to a session-based remote desktop, which is hosted on a Microsoft RDS host, and if the desktop is already set to use a different display protocol, you will not be able to connect immediately. You will be prompted to either use the protocol that is currently set or have the system log you off of the remote operating system so that a connection can be made with the protocol you selected.


After you are connected, the client window appears.
