LU-LU test fails with active as/400 connection (276364)

SYMPTOMS

When a Microsoft SNA Server or Microsoft Host Integration Server operator has an active connection to an AS/400 and then attempts to verify LU 6.2 session availability for a given Advanced Program-to-Program Communications (APPC) triplet (for example, local LU, remote LU, and mode name) by using the APPC Session Viewer utility, and the test fails, look for the following event in the Application Event log:
event id 18

APPC session activation failure: BIND negative response or UNBIND request received

Sense data = 80040000 (NOTE: 0032xxxx indicates UNBIND received)
Connection = connection
LU alias = lu alias
PLU alias = plu alias
Mode name = mode name

CAUSE

SNA Server or Host Integration Server sent a BIND request to start an LU version 6.2 session with the remote system, but the remote system rejected the request for the reason that is indicated in the sense data error. This error is usually caused by a mismatch between the SNA Server or Host Integration Server configuration and the configuration of the remote system (for example, the Local APPC LU name, Remote APPC LU name, or the mode name that is specified in the SNA BIND request may not be configured on the host).

RESOLUTION

Make certain that the "Remote APPC LU" name that is created in the SNA Manager matches the "Local Control Point Name" on the AS/400.
