This month Microsoft released an important hotfix to address a DirectAccess connectivity issue for Windows 7 clients connecting to a Windows Server 2012 DirectAccess Server. The hotfix specifically resolves an issue where Windows 7 clients face a very long delay reestablishing a DirectAccess session using the IP-HTTPS IPv6 transition protocol after recently disconnecting from a VPN session. In this scenario, Windows 7 DirectAccess clients may take as long as 15 minutes to automatically reestablish a DirectAccess session using IP-HTTPS. During this time the IP-HTTPS adapter state is displayed as disconnected. Refer to Microsoft KB 2796313 more information and to download the hotfix.
