Network node server not required: Sent by an APPN end node control point to a network node control point (1) to deactivate CP-CP sessions with the NNCP, or (2) to reject a CP-CP session BIND from the NNCP. The end node no longer requires network node services from the receiver.
VTAM® hint: A possible cause of this error is that the network node server for the CP-CP session attempt is not in the network node server list.
