You cannot create a session collection and an error occurs in Windows Server 2012

This article provides a solution to an issue where you can't create a session collection correctly.

Applies to:   Windows Server 2012 R2
Original KB number:   3014614

Symptoms

Consider the following scenario:

  • You enable the one of the following Group Policy settings on a Windows Server 2012-based server:

    • Require user authentication for remote connections by using Network Level Authentication
    • Set client connection encryption level
    • Use the specified Remote Desktop license servers

  • You create a session-based desktop deployment.

In this scenario, the session collection deployment fails with an "Unable to create the session collection" error message. In addition, the RemoteApp programs that are being created are canceled.

Additionally, if you create a session collection individually, you receive the following error message:

Unable to configure the RD Session Host Server <server name>. Invalid operation

Note

The Group Policy settings are under the following Group Policy paths:

  • Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Security
  • Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Licensing

Workaround

To work around this issue, apply the Group Policy settings that are mentioned in the Symptoms section after you create the Session Collection.

Status

Microsoft has confirmed that it's a problem in the Microsoft products that are listed in the Applies to section.
