SNA Server APPC Returns AP_BAD_PARTNER_LU_ALIAS in Error

ID: Q170422

The information in this article applies to:

Microsoft SNA Server, versions 2.11, 3.0

SYMPTOMS

If an APPC (or CPIC) application attempts to allocate a conversation using a Local APPC LU alias that is owned by an SNA Server that is not running, SNA Server incorrectly returns the following error to the APPC application:

primary_rc = AP_PARAMETER_CHECK (0x0001)
secondary_rc = AP_BAD_PARTNER_LU_ALIAS (0x0000015B)

APPC should return primary_rc = AP_COMM_SUBSYSTEM_NOT_LOADED (0xF004), to indicate that the server is not running, instead of indicating that the partner LU alias is invalid.

CAUSE

This problem was introduced in SNA Server 3.0 as part of the new support for dynamic APPC LU partnering, where the wrong initial return code was being set.

RESOLUTION

An update to SNA Server 3.0 (post SP1) is available to correct this problem.
The updated module is SNASERVR.EXE.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 3.0 and 3.0 SP1. A supported fix is now available but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Product Support Services for more information.
