You are currently offline, waiting for your internet to reconnect

Long reconnection time after a DirectAccess server disconnects a Windows 7-based DirectAccess client

Symptoms
Consider the following scenario:
  • You configure a DirectAccess server together with the support of Windows 7-based clients on a server that is running Windows Server 2012 in a network environment. 
  • You have a Windows 7-based DirectAccess client that is connected to the server by using the IP over HTTPS (IP-HTTPS) protocol.

    Note When you set up the IP-HTTPS protocol, Windows installs an IP-HTTPS adapter on the computer.
  • The DirectAccess client is also connected to a corporate network by using a virtual private network (VPN) connection.
  • You disconnect the VPN connection on the DirectAccess client.
In this scenario, the client requires up to 15 minutes to automatically reconnect to the DirectAccess server after the VPN connection is disconnected. Additionally, the IP-HTTPS adapter state is displayed as disconnected during this time.
Cause
This issue occurs because the IP-HTTPS protocol cannot manage eligible interfaces if you disconnect or connect the VPN interface. Therefore, the Network Change Notification handler is missing. Additionally, this issue occurs because the Internet connectivity timer is not reset when the VPN connection is disconnected.
Resolution

Windows 7 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    VersionProductMilestoneService branch
    6.1.760 0.16xxxWindows 7 RTMGDR
    6.1.760 0.21xxxWindows 7RTMLDR
    6.1.760 1.22xxxWindows 7 SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
