Cancelling SNA Windows 95 Logon Causes Sbpuinit() rc = 563

The information in this article applies to:

• Microsoft SNA Server, versions 2.11, 2.11 Service Pack 1 (SP1), 2.11 SP2, 3.0, and 3.0 SP1

SYMPTOMS

When an SNA Server 3270 EIS application calls sbpuinit() on a Windows 95 client configured to use a non-named pipe transport (for example, TCP/IP sockets, IPX/SPX, or Banyan IP), the SNA client software displays a user logon dialog box. If the user cancels this logon dialog box, the sbpuinit() function returns incorrectly with error 563 (DMDSTFL, or "service table full"), instead of error 625 (DMNONAP, or "NAP not up when starting service").

These error codes are documented in the SNA Server Emulator Interface Guide and \SDK\INC\FMI.H include file, which ships on the SNA Server compact disc.

CAUSE

The SNA Server Windows 95 Snadmod.dll does not retrieve the correct error to the sbpuinit() function when the logon dialog box is cancelled.

STATUS

Microsoft has confirmed this to be a problem in the SNA Server Windows 95 client version 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack.
