SYMPTOMS

Consider the following scenario. On a domain controller, you configure some password policy settings. For example, you configure the Minimum password age password policy or the Password must meet complexity requirements password policy. However, when a domain user tries to change the password of a Windows Vista-based client computer in the domain, the user may receive the following error message:

Status: C000006C/C000006C

This error message contains only the status code. Therefore, the user does not know the meaning of the error message.

This problem occurs if the following conditions are true:

• The user does not meet some password policy requirements when the user changes the password.
• The client computer is running the German version of Windows Vista.

CAUSE

This problem occurs because of an error in the Authui.dll file. Currently, Windows Vista allocates a buffer of only 256 characters for an error message. If an error message is longer than 256 characters, Windows Vista resets the buffer by using the status code only.

The German version of this error message is longer than 256 characters. Therefore, the user receives the error message that contains only the status code.
