Symptoms

Consider the following scenario:

  • On a server that is running Windows Server 2008 R2, Remote Desktop Services runs in Remote Administration mode.

  • An administrator creates an administrative session to the server by using Remote Desktop Connection.

  • The administrator is prompted by a dialog box to disconnect a session to run the newly created session.

In this scenario, the dialog box lists both the administrative sessions and the console sessions on the server. Then, Remote Desktop Services does not protect the console sessions from being disconnected. If the administrator disconnects the console session, applications that are running in the console session may not function correctly.For example, consider the following specific scenario:

  • The UserA user account logs on to a console session on a Windows Server 2008 R2-based remote desktop server.

  • The UserB user account creates an administrative session to the same remote desktop server.

  • The UserC administrator user account creates a third administrative session. UserC is prompted to disconnect a session so that the third session can be created.

In this case, Remote Desktop Services does not protect the console sessions from being disconnected.

Resolution

After you install the following hotfix, the console session is not listed in the dialog box when you are prompted to disconnect a session.
