IBM Client Access/95 Setup Stops Responding

 Last reviewed: April 17, 1997

The information in this article applies to:
  • Microsoft SNA Server, version 2.11 Service Pack 1

SYMPTOMS

When you run IBM Client Access for Windows 95 over the SNA Server 2.11 Service Pack 1 for Windows 95 client software, the Client Access setup program stops responding when configuring connections to multiple AS/400's through SNA Server. After pressing CTRL+ALT+DEL, the following appears in the Close Program dialog box: 

   AS400 Connections - Primary Environment (Not Responding)
Closing this application succeeds.

When you look at the SNA Server Windows 95 client traces, you see that IBM Client Access 95 uses the APPC DISPLAY function to dynamically retrieve configured APPC LU's. The first call to DISPLAY succeeds, although the next attempt fails with STATE_CHECK. The following DISPLAY call stops and never returns.

CAUSE

When the application issues the WinAPPCCleanup() call, the SNA Windows 95 client "DMOD" removes all of the routing procedures for the application. When the application issues the WinAPPCStartup() call again, the DISPLAY library does not register its routing procedure again, and therefore it can never receive any more messages.

RESOLUTION

To resolve this problem, obtain the hotfix mentioned below. The updated files are Wappc32.dll and Winmgt32.dll.

STATUS

Microsoft has confirmed this to be a problem in the Windows 95 client included with SNA Server 2.11 Service Pack 1. 

 A supported fix is now
available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
