Security Update for Windows XP (KB2862152) 1.0

As part of security update 2862152, DirectAccess enforces more checks in IPsec negotiation in certificate authentication methods (for Windows 7, Windows Server 2008 R2, Windows XP, and Windows Server 2003) and KerbProxy authentication (for Windows 8, Windows Server 2012, Windows 8.1, and Windows Server 2012). The security update strengthens how the identity of remote DirectAccess servers is validated if there is a remote connection from a DirectAccess client. The installation of this update is a three-step process.
