The Virtual Desktop Agent has to be present on the virtual machines (VMs) and physical machines to which your users will be connecting. It enables the machines to register with controllers and manages the HDX connection between the machines and the user devices.
If you are using XenDesktop or Provisioning Services to provision VMs, you need to install and configure the Virtual Desktop Agent only once, but if you are using separate stand-alone virtual or physical machines you must install it on each of the machines so they can register with the controller to allow user connections.
You can install the Virtual Desktop Agent from a console session or from an RDP session, but installing from an ICA session is not supported.
To install the Virtual Desktop Agent components from the command line, see XenDesktopVdaSetup.exe in the XenDesktop 5 product documentation in the Citrix eDocs Archive.
The AutoSelect.exe file performs a wizard-based installation of the Virtual Desktop Agent:
A summary of what is going to be installed appears.
VM hosted apps requires desktops and controllers to have synchronized system clocks. This is required by the underlying Kerberos infrastructure that secures the communication between the machines. You can use normal Windows domain infrastructure to ensure that the system time on all machines is correctly synchronized.
To add or remove components, use the Windows control panel. Select Citrix Virtual Desktop Agent. You can then select to add, remove, or reconfigure components, or to remove the Virtual Desktop Agent completely.
The Reconfigure Components option enables you to update the site and port numbers.
To enable users to connect to virtual desktops, you must configure your virtual desktop firewall as follows:
For communication between user devices and virtual desktops:
For communication between controllers and virtual desktops:
%Program Files%\Citrix\XenDesktop\WorkstationAgent.exe requires inbound HTTP (http.sys) on the TCP/IP port you configured at installation time. The default port is 80. Because this connection uses a kernel driver, you may need to configure this setting as a port exception rather than a program exception, depending on your firewall software. If you are running Windows Firewall, you must configure this setting as a port exception.
If you are using Active Directory in your environment, you can deploy the Virtual Desktop Agent to all machines in a domain or Organizational Unit (OU) using Group Policy Objects(GPO).
After you save the new GPO, the Virtual Desktop Agent is installed on computers within the specified OU next time they are restarted.
You can restart computers in the OU remotely by running the #shutdown -r -m command.
For more information about using Active Directory, see the Microsoft Active Directory documentation.
