DOCUMENT:Q161195 13-JUN-2001 [sna] TITLE :OtherServers Parameter Fails on SNA Server 2.11 SP1 Clients PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:2.11 SP1 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, version 2.11 SP1 ------------------------------------------------------------------------------- SYMPTOMS ======== SNA Server 2.11 Service Pack 1 clients cannot connect to SNA Servers outside of their SNA subdomain, even though the OtherServers parameter is configured. The SNA Server 3270 applet returns the following error message when this problems occurs: No SNA Server found in domain. The SNA Server 5250 applet returns the following error message when this problem occurs: SNA Server has not been started. Contact System Administrator. Primary Return Code = F004 Secondary Return Code = 010000F0 NOTE: This problem does not occur with the SNA Server 2.1 or 2.11 clients. CAUSE ===== SNA Server 2.11 Service Pack 1 improved the resource location algorithm that SNA Server clients use to locate an available LU/Pool for both APPC and EIS/3270 applications. The changes made to the resource location algorithm caused a problem in which SNA Server 2.11 Service Pack 1 clients do not attempt to connect to SNA Servers configured with the OtherServers parameter. SNA Server Service Pack 1 clients only try to connect to the computer running SNA Server in the client's SNA subdomain that are returned by the Sponsor server in the Get Server List RPC response. NOTE: This problem only occurs if the LU/Pool that is trying to be accessed by the client is explicitly configured in the emulator/application. For 3270 emulators, the LU/Pool always has to be specified, so the problem occurs consistently. For 5250/APPC applications, the problem does not occur if the Local LU Alias is left blank. RESOLUTION ========== Microsoft has updated the following files to correct this problem: Windows 3.x Client: \system\wdmod.dll Windows 95 Client: \system\snadmod.dll Windows NT Client: \system\snadmod.dll STATUS ====== Microsoft has confirmed this to be a problem in SNA Server version 2.11 Service Pack 1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
