DOCUMENT:Q153411 13-JUN-2001 [sna] TITLE :Default APPC Are Not Resolved Correctly for OS/2 Clients PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:2.1,2.11 OPER/SYS: KEYWORDS:kbenv ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 2.1, 2.11, on platform(s): - the operating system: Microsoft Windows NT ------------------------------------------------------------------------------- SYMPTOMS ======== APPC applications using the Microsoft SNA OS/2 client that make a call to a default local LU or remote LU may fail. CAUSE ===== The TP_STARTED verb is passing a local LU alias of all zeroes. Therefore the APPC library goes into default LU processing, which is to query the user record from the SNA server. For OS/2, this is done by calling the sepdcrec()function. The wrong information is being returned on this call, which is causing the APPC library to believe that the LU alias for this user is a one byte value of 0x01. When the APPC library tries to use this as the local LU alias, the SNA Server rejects it. The OS/2 APPC library's support for extracting a local LU for a particular user was broken when the OS/2 DMODs sepdcrec() processing was changed to use RPC calls to query the server. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft SNA Server versions 2.1 and 2.11. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
