SYMPTOMS
If you change your password on a Microsoft Windows XP-based computer that is a member of a domain, you receive the following error message:

The user name or old password is incorrect. Letters in passwords must be typed using the correct case. Make sure the Caps is not accidentally on.

This symptom occurs if all the following conditions are true:  You are using your user principal name (UPN) to change your password. For example, you are using @  to change your password. The Security Accounts Manager (SAM) account user name is different from the first part of the UPN.

Note The SAM account uses the following format:

\

 You are logging on to a domain of a different forest, and the computer that you use is not a member of the domain to which you are logging on. The trusted domain to which you log on is not using Microsoft Windows Server 2003 forest trust.



CAUSE
This problem occurs because of the resolution between the UPN and the SAM account user name. The resolution is not targeted at a domain controller in the user's domain. The client computer sends the first part of the UPN to the domain controller instead of sending the SAM account user name. After the client sends the first part of the UPN, the symptom that is listed in the &quot;Symptoms&quot; section occurs.
