DOCUMENT:Q196327 13-JUN-2001 [sna] TITLE :Access Violation When 2 LUs have Same Name & Same Connection PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:3.0,3.0 SP1,3.0 SP2,3.0 SP3,4.0,4.0 SP1 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 3.0 SP3, 4.0, 4.0 SP1 ------------------------------------------------------------------------------- SYMPTOMS ======== It is possible to get an access violation when trying to add a remote Advanced Program-to-Program Communications (APPC) logical unit (LU) using the same alias as an already existing remote APPC LU on the same connection. Microsoft SNA Server Manager will first give a warning message in a dialog box: The LU Alias has already been use. The LU Alias cannot be the same as any other APPC LU on its connection. After you click OK to get rid of that dialog box, and then click OK on the Remote APPC LU Properties dialog box, an Application Error in Snaexp.exe may occur. RESOLUTION ========== Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0 SP1, 3.0 SP2, 3.0 SP3, 4.0, and 4.0 SP1. We are researching this problem in SNA Server version 3.0 and will post more information here in the Knowledge Base as it becomes available. This problem was corrected in the latest SNA Server version 4.0 U.S. Service Pack.
