SYMPTOMS
The following APPC verbs are not available for use with SNA Server:
 * Activate_session
 * Deactivate_session

Please refer to the APPC Programmer's Guide included with the SNA Server Software Development Kit for information on the APPC verbs supported by SNA Server.



CAUSE
The APPC Library included with SNA Server was not written to include support for these two APPC verbs.



RESOLUTION
Microsoft has confirmed this to be a problem in SNA Server versions 2.11, 2.11 SP1, 2.11 SP2, 3.0, 3.0 SP1, 3.0 SP2, 3.0 SP3, 4.0, and 4.0 SP1. We are researching this problem in SNA Server versions 2.11 and 3.0 and will post more information here in the Knowledge Base as it becomes available.

This problem was corrected in the latest Microsoft SNA Server version 4.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
This update adds support for the ACTIVATE_SESSION and DEACTIVATE_SESSION APPC verbs to the SNA Server's 32-bit APPC library. Therefore, these verbs are supported on SNA Server systems, SNA Server Client for Windows NT systems, and SNA Server Client for Windows 9x systems.

ACTIVATE_SESSION: Requests SNA Server to activate a session between the Local APPC LU and a specified Partner APPC LU, using a specified APPC Mode. This verb completes either when the specified session has become active or when it has failed.

DEACTIVATE_SESSION: Requests SNA Server to deactivate a particular APPC session or all APPC sessions on a particular APPC Mode.

Please refer to the updated APPC Programmer's Guide in the SNA Server SDK for complete details on these verbs.
