To connect to a remote desktop or published application, you must provide the name of a server and supply credentials for your user account.

About this task

If your system administrator instructs you to configure the certificate checking mode, see Setting the Certificate Checking Mode in Horizon Client.


Obtain the following information from your system 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 to log 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. Double-click the VMware Horizon Client desktop shortcut or click Start > Programs > VMware Horizon Client.
  3. (Optional) To log in as the currently logged-in Windows domain user, click the Options button on the menu bar and select Log in as current user.

    This setting is available only if the Log in as current user feature is installed on the client system.

  4. Double-click the + Add Server button if no servers have yet been added, or click the + New Server button in the menu bar and enter the name of a server, and click Connect.

    Connections between Horizon Client and the server always use SSL. The default port for SSL connections is 443. If the server is not configured to use the default port, use the format shown in this example:

    You might see a message that you must confirm before the login dialog box appears.

  5. If you are prompted for RSA SecurID credentials or RADIUS authentication credentials, enter the user name and passcode and click Continue.
  6. In the login dialog box, enter your user name and password, select a domain, and click Login.

    If you selected Log in as current user in the Options menu and you are authorized to log in to the server, you are not prompted to enter a user name and password.

    If you enter the user name as username@domain, it is treated as a user principal name (UPN) because of the at-sign (@), and the Domain drop-down menu is disabled.

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

  7. If you are prompted to install applications or desktops to the Start menu, click Yes or No.

    This prompt can appear the first time you connect to a server on which shortcuts have been configured for published applications or remote desktops. If you click Yes, Start menu shortcuts are installed on the client system for those published applications or remote desktops, if you are entitled to use them. If you click No, Start menu shortcuts are not installed. In some companies, shortcuts are installed automatically and you are not prompted.

  8. (Optional) To configure display settings for remote desktops, either right-click a desktop icon or select a desktop icon and click the Settings (gear-shaped) icon next to the server name in the upper portion of the window.



    Display protocol

    If the Horizon administrator has allowed it, you can use the Connect Via list to select the display protocol. To use VMware Blast, Horizon Agent 7.0 or later must be installed.

    Display layout

    Use the Display list to select a window size or to use multiple monitors.

  9. To connect to a remote desktop or application, either double-click its icon or right-click the icon and select Launch from the context menu.

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


After you are connected, the remote desktop or application window appears. If you are entitled to more than one desktop or application, the desktop and application selector window also remains open, so that you can connect to multiple items at the same time.

If the client drive redirection feature is enabled, the Sharing dialog box appears and you can allow or deny access to files on the local file system. For more information, see Share Access to Local Folders and Drives with Client Drive Redirection.

After a successful connection is made, an icon for this server is saved to the Horizon Client home window. The next time you use Horizon Client to connect to this server, you can double-click the icon, or, if you use only this one server, you can right-click the icon for the server and select Autoconnect to this Server from the context menu.

What to do next

If you connected to a remote desktop and you want to connect to this remote desktop each time you log in, select Autoconnect to this Desktop from the Options menu in the desktop.
