FIX: A remote desktop session cannot start after you add a new user to a computer that is running Windows 7 Service Pack 1 or Windows Server 2008 R2 Service Pack 1

Applies to: Windows 7 Service Pack 1Windows Server 2008 R2 Service Pack 1

Symptoms


Consider the following scenario:
  • You have a computer that is running Windows 7 Service Pack 1 or Windows Server 2008 R2 Service Pack 1.
  • You set up a new user in a local group and add that group to the RDP-TCP Listener Discretionary Access Control List (DACL).
  • You try to start a new remote desktop session to your computer by using the new user's credentials.

In this scenario, the remote desktop session does not start. Only when you restart the terminal service or restart the server can the remote desktop session be established.

Cause


This problem occurs because the listener thread does not update the RDP-TCP Listener DACL changes correctly.
