ERROR_TS_INCOMPATIBLE_SESSIONS
ERROR_TS_INCOMPATIBLE_SESSIONS means the requested operation involves two session types or states that Windows cannot combine. It can occur when trying to attach, transfer, shadow, or otherwise manage a session using an incompatible context.
What to check
- List both the current and target sessions and identify their IDs, users, states, and connection types.
- Confirm that the administrative command is supported for the target session type rather than assuming console and remote sessions are interchangeable.
- Retry from a supported administrative context after verifying the target session is active and eligible for the operation.
