DOCUMENT:Q137308 13-JUN-2001 [sna] TITLE :SNA Server Windows 3.x APPC Display Call May Cause GP Fault PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:2.0,2.1,2.11 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 2.0, 2.1, 2.11, on platform(s): - the operating system: Microsoft Windows NT ------------------------------------------------------------------------------- SYMPTOMS ======== If a Windows 3.x program calls the APPC DISPLAY verb and uses the CSEXTNIDCSLISTND option to return a list of active SNA Servers in the domain, the program may encounter an application exception in WINMGT.DLL, WDMOD.DLL, application DLL, or may cause the computer to stop responding (hang). For backwards compatibility, SNA Server included the APPC Display verb CSEXTNIDCSLISTND for applications written to talk to IBM ES for OS/2 version 1.0. This problem occurs only if there are no SNA Servers in the domain that are configured to support a Netview connection. CAUSE ===== The winmgt calls the SNAReleaseBuffer with a random memory address and releases a random memory segment (stack, dgroup or code). RESOLUTION ========== Microsoft has updated the file WINMGT.DLL to correct this problem. STATUS ====== Microsoft has confirmed this to be a problem in SNA Server for Windows NT. This problem was corrected in the latest SNA Server for Windows NT, 2.11 U.S. Service Pack.
