Yes, if you can Disconnect or Logoff a session if you know (or obtain) the SessionID.
See
WTSDisconnectSession and
WTSLogoffSession. Delphi translations are in JwaWtsApi32 from the
Jedi Apilib
Edit: sorry I didn't notice that this was a multipage thread, I was replying to:
Zitat:
Gibt's da nicht auch die entsprechenden APIs für?
from page 1
Edit2: Still after reading the rest of the topic, if you use either WTSDisconnectSession or WTSLogoffSession on the pc the session is running at you can achieve what you want.
