DOCUMENT:Q158270 13-JUN-2001 [sna] TITLE :SNA 2.11 SP1 Win 3.x Client Logon Fails if NT Password Expired PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:2.11 SP1 OPER/SYS: KEYWORDS:kbinterop ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, version 2.11 SP1 ------------------------------------------------------------------------------- SYMPTOMS ======== If you use SNA Server version 2.11 Service Pack 1 (SP1) Windows 3.x client software, and you connect to SNA Server over TCP/IP sockets, NetWare IPX/SPX, or Banyan IP, you may experience the following problem. The SNA Server 2.11 SP1 Windows 3.x client software supports the ability for SNA client users to change their Microsoft Windows NT password, if the Windows NT administrator has configured their user accounts to User Must Change Password at Next Logon. However, if the Windows NT password has expired, the SNA client logon fails with the following error messages and never prompts the user to enter a new password: SNA Server Logon Error The logon attempt to SNA Server failed due to a bad user ID, password or domain. SNA Server Error: 546 Cannot establish connection with SNA Server CAUSE ===== SNA Server was not checking the SubStatus return value from the LsaLogonUser() call, and only checking the main return code, which Windows NT sets to STATUS_ACCOUNT_RESTRICTION (0xC000006E) when the user's password has expired. If the user account is configured to require a password change at next logon, Windows NT returns a return code of STATUS_PASSWORD_MUST_CHANGE, so this problem did not occur. RESOLUTION ========== A hotfix to SNADMOD.DLL is available that corrects this problem. SNA Server now checks the SubStatus return value from the LsaLogonUser() call if the return code is STATUS_ACCOUNT_RESTRICTION. If the SubStatus is set to STATUS_PASSWORD_EXPIRED, SNA Server notifies the SNA Win 3.x client software to prompts the user to enter a new password. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft SNA Server version 2.11 Service Pack 1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
