SNA Server APPC Returns AP_BAD_PARTNER_LU_ALIAS in Error

Article ID: 170422

APPLIES TO

  • Microsoft SNA Server 3.0
  • Microsoft SNA Server 3.0 Service Pack 4



This article was previously published under Q170422


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. This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
