- TITLE :INF: Password Case Sensitivity and System Error 1219
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:

- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- --------------------------------------------------------------------
-
- Summary:
-
- 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.
