  2. You cannot log on to a virtual machine that is running Windows 8 or Windows Server 2012 in a VDI environment

You cannot log on to a virtual machine that is running Windows 8 or Windows Server 2012 in a VDI environment

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You deploy a Virtual Desktop Infrastructure (VDI) environment in a network.
  • You enable the Remote Desktop Virtualization Host (RD Virtualization Host) role service on the Windows Server 2012-based computers.
  • You try to log on to a virtual machine that is running Windows 8 or Windows Server 2012 in the VDI environment.
In this scenario, you cannot log on to the virtual machine. The logon screen appears but the logon process cannot be completed.

Notes

  • The previous corresponding remote session to the RD Virtualization Host does not log off.
  • You may receive the following error message when you try to manually logoff the session in the Server Manager console:

    RD Connection Broker failed to process the connection request for user <domain>\<userid>.
    Failed while checking for disconnected session.
    Error: User is trying to connect to the same Pool more than once simultaneously.

Cause

This issue occurs because the host computer does not receive a notification that the previous session has ended during the logoff operation. Therefore, the previous session does not log off successfully.
