STATUS_CTX_WINSTATION_NAME_INVALID

The request used the wrong kind of session identifier

STATUS_CTX_WINSTATION_NAME_INVALID concerns the Remote Desktop Services session namespace, historically called a WinStation. It does not identify a failed DNS lookup or an unreachable computer. The server rejected the session name supplied to a session-management operation before it could act on a session.

Modern Remote Desktop Services APIs expose a numeric session ID together with session information. A user name, an RD Session Host name, a listener name, and a session name are different identifiers; substituting one for another can make an otherwise valid management request target nothing useful.

Useful evidence

Enumerate sessions on the intended RD Session Host and record the numeric session ID, session state, user, and server before issuing the follow-up operation.
Record the exact caller API or command and the identifier it accepted. This status is most useful when it identifies an application that constructed a session name instead of reading the current session list.
If a connection broker or gateway is in front of the host, confirm that the session-management request is sent to the host that actually owns the session.
