By: Jordan Krause

Overview of this book

DirectAccess is an amazing Microsoft technology that is truly the evolution of VPN; any Microsoft-centric shop needs this technology. DirectAccess is an automatic remote access solution that takes care of everything from planning to deployment. Microsoft DirectAccess Best Practices and Troubleshooting will provide you with the precise steps you need to take for the very best possible implementation of DirectAccess in your network. You will find answers to some of the most frequently asked questions from administrators and explore unique troubleshooting scenarios that you will want to understand in case they happen to you. Microsoft DirectAccess Best Practices and Troubleshooting outlines best practices for configuring DirectAccess in any network. You will learn how to configure Manage Out capabilities to plan, administer, and deploy DirectAccess client computers from inside the corporate network. You will also learn about a couple of the lesser-known capabilities within a DirectAccess environment and the log information that is available on the client machines. This book also focuses on some specific cases that portray unique or interesting troubleshooting scenarios that DirectAccess administrators may encounter. By describing the problem, the symptoms, and the fixes to these problems, the reader will be able to gain a deeper understanding of the way DirectAccess works and why these external influences are important to the overall solution.

IPv6 is essentially the reason why Manage Out does not work until we make some additions to your network. "But DirectAccess in Server 2012 handles all of my IPv6 to IPv4 translations so that my internal network can be all IPv4, right?" The answer to that question is yes, but those translations only work in one direction. For example, in our previous Group Policy processing scenario, the client computer calls out for Active Directory, and those packets traverse the DirectAccess tunnels using IPv6. When the packets get to the DirectAccess server, it sees that the Domain Controller is IPv4, so it translates those IPv6 packets into IPv4 and sends them on their merry way. Domain Controller receives the said IPv4 packets, and responds in kind back to the DirectAccess server. Since there is now an active thread and translation running on the DirectAccess server for that communication, it knows that it has to take those IPv4 packets coming back (as a response...
