SYMPTOMS

A user in an external Kerberos realm logs on to a Microsoft Windows XP Professional-based computer or to a Microsoft Windows 2000 Professional-based computer in a child domain. Group Policy settings from a Microsoft Windows Server 2003-based domain controller in the parent domain are not applied.

CAUSE

This issue occurs because of increased security in Microsoft Windows Server 2003.

RESOLUTION

This is a client-side fix. To resolve the issue, you must, at a minimum, install the hotfix on all client computers in the child domain. You must apply the hotfix to the following computers:
  • Windows Server 2003-based clients in the child domain
  • Windows XP Professional-based clients in the child domain
  • Windows 2000 Professional-based clients in the child domain
If any one of the Windows 2000-based or Windows Server 2003-based servers or domain controllers are performing client-side authentication requests for external Kerberos realm accounts, the hotfix should also be installed on these computers.

Note This problem does not just apply to child domains. This problem can occur across other transitive trust relationships. For example, the problem can occur in a domain in a different tree if a trusting domain in the same forest trusts an external Kerberos realm.

WORKAROUND

To work around this issue, use one of the following methods:
  • Match the passwords for the external user account and for the currently mapped Windows user account in the parent domain.
  • Map the external Kerberos realm user account to an account in the child domain.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows Server 2003 Service Pack 2.

MORE INFORMATION

This issue occurs after the following sequence of events:
  1. The Kerberos client queries the external realm to obtain the domain controller account.
  2. The external realm does not have the domain controller computer account from the parent domain. Therefore, the external realm returns a response of "unknown principal."
  3. The Kerberos client queries the child domain to obtain the domain controller account.
  4. The child domain issues a cross-realm Ticket Granting Ticket (TGT). Because the original TGT from the external realm does not contain a Privilege Attribute Certificate (PAC), the child domain creates a new PAC. This new PAC contains the parent domain groups to which the user belongs.
  5. The Kerberos client follows the referral to the parent domain. When the parent domain receives a cross-realm TGT that contains a PAC that includes security identifiers (SIDs) from its own domain, the parent domain refuses the TGT.
Windows Server 2003 security features verify that SIDs from a Key Distribution Center (KDC) in a trusted realm are not included in the PACs from another realm. This behavior helps prevent KDCs from obtaining increased rights in a realm that the KDCs do not maintain.

With this hotfix, the client computers can negotiate the trust path successfully. The client computers avoid the situation where a Windows Server 2003 KDC is presented with a PAC that includes SIDs from the Windows Server 2003 realm.

Windows 2000 Server does not have this additional SID filtering capability. Therefore, this issue does not occur in a Windows 2000 Server-based domain.

Technical support for x64-based versions of Microsoft Windows

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
