Product: Microsoft SNA Server for Windows NT v2.0 Update: Patch #37 (includes Patch #5, 11 and 34) Status: Confirmed

PKZIP 2.04g format -- uncompress using the "-d" option.

Date: March 18, 1994

Modules updated:

\SYSTEM\SNASERVR.EXE  03/16/94  02:35p  524800  (2.0.0.142) Bugs fixed:

2073 SNA Server internal gateway error (event 29, sense code 4596).

Observed when using the "exit all" option with the IBM PCOM 3270 emulator running as a downstream PU to SNA Server. If an outage occurs from a downstream PU after an Unbind request is sent to the host, but the Unbind response not yet received, SNA Server sends a termself (which the host rejects). However, the host then sends the Unbind response which the server is not expecting, so it logs an error and fails to send the Notify(unavail) that the host is expecting. The LU is lost until SNA Server is recycled.

XXXX Invalid SNA Server BIND response leads to sense code 1001000E.

SNA Server responds with all control vectors in response to a host BIND message, though not all control vectors may be valid for the response. This can lead to a host sense code of 1001000E, or invalid bind response.

2020 SNA Server hot backup fix for 5250 users.

When more than one SNA Server is configured to support 5250 sessions (for hot backup purposes) and the link fails on one of the servers, the client occasionally has to reopen a new session twice before getting a session through the backup server.

1739 Server gp-fault when LU pool is opened and connections inactive

Start the SNA Server service but leave all connections inactive. At the client, open an LU Pooled session using the 3270 applet. The customer reports that the SNA Server encounters an access violation, though we have been unable to reproduce the problem.

1765 Automatic 5250 device name generation fails after 10 users

This fix applies if over 10 SNA Server users are using the 5250 applet and sharing the same LU/LU pair when communicating to the AS/400, and they are not specifying their own unique device names when opening a session. Under this situation, SNA Server automatically generates unique device names for each client (to prevent conflicts in the use of device names). However, after 10 users, SNA Server fails to generate valid unique device names.

Update Procedure:

- Stop the SNA Server service

- Copy the updated SNASERVR.EXE over the existing version in the server's

\SYSTEM directory. - Restart SNA Server
