DOCUMENT:Q214571 13-JUN-2001 [sna] TITLE :Duplicate Remote APPC LUs Can Be Created On A Connection PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:3.0,3.0SP1 OPER/SYS: KEYWORDS:kbsna300sp4fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 3.0, 3.0SP1 ------------------------------------------------------------------------------- SYMPTOMS ======== SNA Server versions 3.0 and 3.0 SP1 allow an administrator to create multiple Remote APPC (Advanced Program-to-Program Communications) LUs using the same Fully Qualified LU Name on the same connection. For example, the following are Remote APPC LUs that have unique aliases and the same Fully Qualified LU Name: Remote LU #1: LU Alias: REMOTE1 Network Name: APPN LU Name: REMOTE Remote LU #2: LU Alias: REMOTE2 Network Name: APPN LU Name: REMOTE The Fully Qualified LU Name for each of the Remote APPC LUs is APPN.REMOTE. The following error will be displayed when SNA Server Manager on a SNA Server version 3.0 SP2 or later system is used to open a SNA Server version 3.0 or 3.0 SP1 configuration file (Com.cfg) that contains duplicate Remote APPC LUs on a connection: SnaOle The Fully Qualified LU Name has already been used. The combination of the Net Name and LU Name cannot be the same as any other APPC LU on the server. CAUSE ===== The ability to add Remote APPC LUs using the same Fully Qualified LU Name to the same connection was inadvertantly added to SNA Server versions 3.0 and 3.0 SP1. RESOLUTION ========== SNA Server 3.0 -------------- To resolve this problem, obtain the latest service pack for SNA Server version 3.0. For additional information, please see the following article in the Microsoft Knowledge Base: Q184307 How to Obtain the Latest SNA Server Version 3.0 Service Pack WORKAROUND ========== Remove the duplicate Remote APPC LUs from the SNA Server 3.0 and 3.0 SP1 configurations before upgrading to SNA Server 3.0 SP2 or later. STATUS ====== Microsoft has confirmed this to be a problem in SNA Server 3.0 SP3, 4.0, 4.0 SP1 and 4.0 SP2. This problem was first corrected in SNA Server version 3.0 Service Pack 4 and SNA Server version 4.0 Service Pack 3. MORE INFORMATION ================ Remote APPC LUs with the same Fully Qualified LU Name are allowed on a SNA Server as long as they are defined on different connections. SNA Server versions 3.0 SP2, 3.0 SP3, and 4.0 (all services packs) do not allow duplicate Remote APPC LUs on the same connection. This is the correct and expected behavior.
