ERROR_CTX_SESSION_IN_USE
ERROR_CTX_SESSION_IN_USE means the account already has a session on the target computer and the current policy or session type does not permit the requested additional logon. It is not necessarily a licensing error.
List sessions for the account and inspect the Session Host policy governing multiple sessions or reconnection. Reconnect to the intended existing session or change policy deliberately instead of repeatedly creating a second session.
What to check
- List current and disconnected sessions for the account before attempting another connection.
- Check the effective policy for restricting users to a single session and any application-specific session constraints.
- Reconnect to the existing session where appropriate instead of creating another one.
