For example, after you return to the Terminal Services session, you press the DELETE key while you are working. In this example, the Terminal Services session assumes that you have just pressed CTRL+ALT+DELETE.

Note This issue occurs if the following conditions are true when the computer is locked:

  • The local area network is disconnected and then reconnected.

  • The Terminal Services session requires to be reconnected.
