Applies to: Windows 8.1, Windows Server 2012 R2

July 19, 2019 - IMPORTANT: Beginning with the July 2019 updates, Active Directory domain controllers will intentionally block unconstrained delegation across forest, external, and quarantined trusts.

Administrators should reconfigure the affected services to use resource-based constrained delegation. For more information, see KB4490425.
