SYMPTOMS

Consider the following scenario:
  • You install a GDR for Channel Binding Token (also known as CBT) on a computer that is running Windows XP or Windows Server 2003.
    Note For more information about the GDR for Channel Binding Token, view the following Microsoft Knowledge Base (KB) article:
    968389 Extended Protection for Authentication
  • The computer is joined to a domain whose domain controller (DC) is running Windows Server 2008 R2.
In this scenario, Digest authentication fails.

CAUSE

This problem occurs because of a macro that identifies the size of a hash for a nonce. The value of the macro for Windows Server 2008 R2 differs from the value of the macro for Windows Server 2003 and for Windows XP. This difference causes Digest authentication to fail.
