256986 Description of the Microsoft Windows Registry



SYMPTOMS
When you try to change the logon password on your Windows XP-based computer, you receive the following error message:

The system cannot change your password because the domain  is not available.



CAUSE
This issue occurs when all the following conditions are true:
 * You try to log on to a Microsoft Windows Server 2003-based domain by using a client that is located in a trusted Massachusetts Institute of Technology (MIT) Kerberos realm.
 * Your MIT Kerberos realm account has a password that has expired.
 * When you try to log on the Windows Server 2003-based domain, you are prompted to change your password. You type the old and new passwords in the dialog box, and then you press ENTER.



WORKAROUND
To work around this issue, log on to the Windows Server 2003-based domain by using the User Principle Name (UPN) of the MIT Kerberos realm client. For example, use a UPN that has a structure that is similar to the following:

UserName@MITRealm.CompanyName.com

Note You can restrict a user's computer so that they must use a UPN to log on to the domain. To do this, follow these steps on the Windows XP-based computer that is an MIT Kerberos realm client.

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.  Click Start, click Run, type regedit, and then click OK. Locate and then click the following subkey:

Note If the NoDomainUI entry already exists in the right pane, go to step 5. On the Edit menu, point to New, and then click DWORD Value. Type NoDomainUI, and then press ENTER. Right-click NoDomainUI, click Modify, type 1, and then click OK. Quit Registry Editor.</li> Restart the computer.</li></ol>
