- 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:
