An MIT Kerberos client may receive the following error message:
A ticket that is created by a Windows 2000 Kerberos Key Distribution Center (KDC) always has the key version number set to 1. This value is not incremented when a principal's password is updated. In Windows Server 2003, a new msDS-KeyVersionNumber attribute has been added to the schema. Therefore, this behavior has changed. A Windows Server 2003-based domain controller increments the msDS-KeyVersionNumber attribute whenever the principal's password changes. Tickets that Windows Server 2003-based domain controllers distribute include this updated attribute.
This problem occurs when the value of a principal's msDS-KeyVersionNumber attribute is greater than one, and the principal requests a service ticket from a Windows Server 2003-based domain controller. If the principal's keytab file was created on a Windows 2000-based domain controller, the key version number in the keytab file is 1. In this scenario, the key version number in the client's initial logon request does not match the key version number in the Active Directory directory service. Therefore, authentication does not succeed.
Important After you install this hotfix, see the "More Information" section for steps that you can use to turn on the new behavior.

To turn on the new behavior, modify the dSHeuristic attribute in Active Directory. To do this, follow these steps:
- Start ADSI Edit. To do this, open a command prompt in the Support Tools folder, type adsiedit.msc, and then press ENTER.
Note ADSI Edit is included with the Microsoft Windows 2000 Server Support Tools and with the Microsoft Windows Server 2003 Support Tools. To install the Windows 2000 Support Tools, double-click Setup.exe in the Support\Tools folder on the Windows 2000 CD. To install the Windows Server 2003 Support Tools, double-click Suptools.msi in the Support\Tools folder on the Windows Server 2003 CD.
- Right-click CN=Directory Service in the following location, and then click Properties:CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=forest root
- Click the Attribute Editor tab, and then locate dSHeuristic in the Attributes list.
Note By default, the value of this attribute is not set.
- Click dSHeuristic, and then click Edit.
- Type 00000000010000001 in the Value box, and then click OK.
- The tenth bit from the left must be 1.
- The seventeenth bit from the left must be 1.
- None of the other bits of the existing value should be changed.
To confirm the fix, follow these steps:
- Use ADSI Edit to locate a user account in Active Directory.
- Right-click the user account object, and then click Properties.
- Click the Attribute Editor tab, and then locate msDS-KeyVersionNumber in the Attributes list.
