SYMPTOMS

After you change your logon password from a Macintosh client, you may be unable log on to a Windows 2000 Server-based computer that is running Services for Macintosh from a different Macintosh client.

However, you can log on successfully from a Windows-based client by using the new password. Additionally, if you change your password from a Windows-based client, you can log on successfully from the Macintosh client.

CAUSE

This problem may occur if you change your password from a Macintosh client that uses the Apple User Authentication Module (UAM), and then you try log on to the Windows 2000 Server-based computer from a Macintosh client that uses the Microsoft UAM.

In this scenario, the NT hash is not updated correctly in the Security Account Manager (SAM) database when you change your password from a Macintosh client that uses the Apple UAM.
