AD FS cannot start on a non-English language-based server in Windows Server 2012 R2 or Windows Server 2008 R2

Applies to: Windows Server 2012 R2 DatacenterWindows Server 2012 R2 StandardWindows Server 2012 R2 Essentials


Consider the following scenario:

  •   You have a non-English-language-based server that is running Windows Server 2012 R2 or Windows Server 2008 R2 Service Pack 1 (SP1).
  • You install Active Directory Federation Services (AD FS) on the server.
In this scenario, AD FS cannot start.


This issue occurs because of a mismatch when AD FS writes the date and time objects into the database, and then reads them back as AD FS starts.
