Problems when combining UAG TMG and KMS

Consider the following scenario:

  • You have Microsoft Forefront Threat Management Gateway 2010 installed, or you have Microsoft Forefront Unified Access Gateway 2010 installed, on a server that is running Windows Server 2008 R2.
  • You have not activated Windows Server 2008 R2.
  • You try to activate Windows Server 2008 R2 by using a Key Management Service (KMS) server in your organization.

In this scenario, Windows activation fails, and you receive the following error message:

Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. The Key Management Service (KMS) is unavailable.
