FIX: User accounts that use DES encryption for Kerberos authentication types cannot be authenticated in a Windows Server 2003 domain after a Windows Server 2008 R2 domain controller joins the domain

View products that this article applies to.

Symptoms

Consider the following scenario:

  • A user account is created in a Windows Server 2003 domain.
  • All domain controllers in this domain are running Windows Server 2003.
  • The user account is configured to use Data Encryption Standard (DES) encryption types for Kerberos authentication.
  • A computer that is running Windows Server 2008 R2 joins the domain.
  • Active Directory is installed on the member server.
In this scenario, the user account cannot log on to the domain immediately after the Windows Server 2008 R2 domain controller starts. You may also receive the following error message:
KDC has no support for encryption type while getting initial credentials.
Additionally, the following events are logged in the System log on the domain controller that is running Windows Server 2008 R2:

Description:
While processing an AS request for target service krbtgt, the account name did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 1). The requested etypes : 16 1 11 10 15 12 13. The accounts available etypes : 23 -133 -128. Changing or resetting the password of user_name will generate a proper key.

Description:
While processing a TGS request for the target server server_name, the account account_name did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 9).

Cause

This problem occurs because different data structures are used to save encryption type information about the user account on Windows Server 2003 domain controllers and on Windows Server 2008 R2 domain controllers.

When a user account is created on a Windows Server 2003 domain controller, the encryption type information is saved in a data structure. Then, this information is copied to Windows Server 2008 R2 domain controllers by using AD replication.

Note This problem also occurs when the password of a user account is reset.

When a Windows Server 2008 R2 domain controller authenticates the user account, the domain controller reads this encryption type information from the data structure that is used by the Windows Server 2003 domain controller. It should then copy this encryption type information to a different data structure. However, the information is not copied as expected. Therefore, authentication fails.
