STATUS_CTX_WINSTATION_NAME_COLLISION

The server rejected a duplicate session namespace entry

STATUS_CTX_WINSTATION_NAME_COLLISION indicates that the requested Terminal Services session name already belongs to another object in the relevant server namespace. It is a naming collision, not a collision between two TCP clients that happened to use the same IP address.

The useful question is which operation tried to create or configure the name: a session-management component, listener configuration, test harness, or legacy application. Retrying with the same name repeats the same namespace conflict.

Useful evidence

  • Enumerate current sessions and listeners on the correct RD Session Host, preserving the returned IDs and names as evidence.
  • Identify the code path that generated the name and ensure it derives uniqueness from server state rather than from a reused local counter or cached session record.
  • Do not delete an existing session or listener solely to make the name available until its owner and active users are known.
