Enforcement Client Is Not Initialized

Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2

This problem can occur when the NAP client computer is running Windows Vista® with no service packs installed. Although an enforcement client is initialized, it might not be displayed as initialized when you run the netsh nap client show state command. This is a known issue with computers running Windows Vista that do not have Service Pack 1 (SP1) installed.
