DOCUMENT:Q98724 08-AUG-2001 [winnt] TITLE :Password Case Sensitivity and System Error 1219 PRODUCT :Microsoft Windows NT PROD/VER:3.1 3.51 4.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 3.1 - Microsoft Windows NT Workstation version 3.1 - Microsoft Windows NT Server versions 3.51, 4.0 - Microsoft Windows NT Workstation versions 3.51, 4.0 ------------------------------------------------------------------------------- Password validation in a Windows NT network is case-sensitive as long as the machine you are logged onto and the machine whose resource you are trying to access are both Windows NT machines; the case of the password entered and the password stored in the Windows NT user database must match. However, if a logon procedure takes place on a non-Windows NT machine (a Windows for Workgroups machine, for example) or the share being accessed is on a non-Windows NT server (even if the server is in a Windows NT domain), password validation becomes case- insensitive. There is one exception to these rules and one error that results from mismatched case in passwords. The exception is that if you change your password from a non-Windows NT machine (using the Windows NT NET PASSWORD command), Windows NT stores your new password as a case-insensitive password and permits all subsequent log ons to be password case-insensitive. Even if another user logs on from a Windows NT machine, no password case checking is performed. An error can be generated if you mismatch the case of your password after you've already logged onto a Windows NT domain. For example, if you establish a network session with a Windows NT machine by typing the following two lines net use x: \\ntmachine\data /u:domain\user PASSWORD net use y: \\ntmachine\apps /u:domain\user password the following error message is displayed: System error 1219 has occurred. The credentials supplied conflict with an existing set of credentials. To avoid this error message, make sure you always use the same case when attempting to connect to shared resources.
