If you absolutely must run Windows Server 2008 for legacy hardware or software, ensure you have at least achieved build 6003 through legitimate ESU means, and immediately air-gap the server from the internet. Better yet, virtualize it, snapshot it, and start planning your migration yesterday.

This allowed Windows Server 2008 SP2 to continue receiving critical updates without breaking the Windows update servicing mechanism. Critical Updates Associated with Build 6003 (SHA-2 Support)
