This article describes how to enable connections from Receiver for HTML 5 to Windows 2012 R2 Remote Desktop Services (RDS) desktops deployed using Machine Creation Services (MCS).

Instructions

Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.

The following steps are necessary to allow Receiver for HTML5 connections to Windows 2012 R2 RDS desktops that were created using MCS. On the master image, add the following registry entries:

• From Regedit go to the following location: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\GroupPolicy\Defaults and create a key “ICAPolicies” if not already present.

  Note: This workaround is not recommended in case of a Citrix Deployment using App Orchestration.

• Add the registry keys shown in the following table:

• Shut down the machine and create a new snapshot. Use this snapshot as the master image.

• Do not push the Web Socket Policies to the machines being provisioned using this master image.

Note: You might run rsop.msc on the master image VM and see if the Web Socket policies are available.
