Bugs fixed:

- 2512: WNAP fails to load on Netware connection number 256 or 512.

Due to a restriction of the Netware interface that SNA Server uses, clients who happen to connect using Netware connection number 256 or 512 will not be able to start WNAP due to "no network found" error. This update uses a different mechanism to detect the presence of the Netware shell, rather than using the connection number (which is returned to SNA Server as connection #0).

- XXXX: WNAP support for NetWare User ID defaulting from WIN.INI.

Allows the LogonUserName= entry in the [wnap] section of WIN.INI to default the user id in the SNA Server client logon dialog. Previously, SNA Server retrieved the user name based on the user's Netware connection number. However, if the connection number exceeded 256, the wrong userid would appear in this logon dialog.

- 2452: Improved detection of SPX connection failures.

When connecting over Netware IPX/SPX, the SNA Server client would occasionally not be notified of an SPX session error, causing the SNA application to hang. This update assumes any SPX connection write error should be interpreted as an SPX connection failure, causing SNA Server to cancel any pending reads over that SPX connection.

- XXXX: Miscellaneous APPC TP dynamic load problems on Win 3.x client

When running an APPC or CPIC program which accepts conversations over more than one TP name, the SNA Server client would incorrectly attempt to invoke another copy of the invokable TP rather than route the request to the outstanding receive_allocate or cmaccp call. Update Procedure:

- On an SNA Server Windows 3.x client machine, stop the SNA Server

client software and apply the following updated modules:

save original copies of all files by renaming them to *.OLD

copy all updates from Patch #52 to the SNA client machine (as documented in the Patch 52 readme file)

copy all *.DLL files to the \SYSTEM directory copy WNAP.EXE to the directory

(save the TRACE versions for troubleshooting purposes, if required)

NOTE: If you are using Attachmate Extra 4.0a, this version includes an older set of SNA Server Windows 3.x client files, which are copied to the \EXTRAWIN directory. If applying this update to such a system, rename the following files in the \EXTRAWIN directory so they are not used:

WNAP.EXE  -> WNAP.20 WDMOD.DLL -> WDMOD.20 LMCLI.DLL -> LMCLI.20 NWCLI.DLL -> NWCLI.20 WLOGTR.DLL -> WLOGTR.20 YMGR.DLL  -> YMGR.20 - Restart the SNA client software
