DirectAccess Deep Dive Training at TechMentor 2014

It is with great pleasure that I announce that I’ll be delivering a comprehensive, three-hour deep-dive training session at the TechMentor 2014 conference this year. The conference will be held August 11-15, 2014 in Redmond, WA. During the session you’ll learn how to design, plan, implement, and support DirectAccess running on Windows Server 2012 R2. If you’re considering deploying DirectAccess this year, you won’t want to miss out on this event. If you register before June 4 you can save $300.00, so register today!

DirectAccess Network Deployment Scenarios

When DirectAccess was first introduced in Windows Server 2008 R2, and continuing with Forefront Unified Access Gateway (UAG) 2010 DirectAccess, there was a hard requirement for the DirectAccess server to be configured with two network interfaces; one internal, and one external. The external network interface also required two consecutive public IPv4 addresses and did not support placement behind a Network Address Translation (NAT) device.


Windows Server 2012 DirectAccess and Forefront UAG 2010 - Better Together

When DirectAccess was first introduced as a feature of Windows Server 2008 R2, many considered the concept of always-on, secure remote access a natural evolution of traditional Virtual Private Networking (VPN) technologies. VPN had gone from being something that only IT administrators needed to provide remote support for their systems to an essential productivity tool for the modern, mobile workforce. Unfortunately, DirectAccess in Windows Server 2008 R2 was a bit ahead of its time. The idea was an excellent one, but in practice it was difficult to implement and carried steep infrastructure requirements, the most challenging of those being the requirement to deploy IPv6 on the internal network.

Secure Remote Access to On-Premises Private Cloud Resources with Microsoft Windows DirectAccess

Here on the Iron Networks Cloud Infrastructure Blog we talk quite a bit about the Microsoft private cloud with Hyper-V and System Center. We’ve extolled the virtues of the Microsoft Private Cloud stack with Windows Server 2012 R2 Hyper-V and System Center 2012, the building blocks for deploying scalable, highly available systems to support agile and dynamic workloads. The vision of the modern datacenter is at the heart of some very exciting technology and solutions, such as the Iron Networks IronPOD.

Why is UAG DirectAccess better than traditional VPN?

In our previous post at http://www.nappliance.com/blog/nappliance-nuag-and-directaccess-better-together we highlighted how UAG and DirectAccess are better together and the benefits of connecting through the DirectAccess. In this post we will concentrate on the advantages DirectAccess has over the traditional VPN connectivity and why companies would want to move away from the VPN infrastructure.

UAG 2010: Error "Applying Network Access Protection configuration failed"

 

Problem:

When trying to activate the configuration on a UAG server, you might find that the activation failed and you can see the following error messages in the status window:

Error: Applying Network Access Protection configuration failed.

UAG 2010: Error "An unknown error occurred while processing the certificate. Contact the site administrator"

A client that is trying to access an SSL enabled application on a backend server (e.g. Exchange) that is published through the Forefront UAG portal gets an error, specifically:

“An unknown error occurred while processing the certificate. Contact the site administrator”.

The cause:

UAG 2010 RTM: Integrating NAP Policies

Microsoft UAG 2010 can be integrated with Windows NAP (Network Access Protection) to make sure that the computers comply with the IT policies before user’s login into the UAG portal. Windows Network Access Protection is part of Windows 2008 and 2008 R2 servers. No extra hardware or licensing is required to implement Microsoft NAP in an environment. Moreover, there are simple settings in UAG for integrating NAP to do policy enforcement.

UAG 2010: Removing an Installed UAG Update from nUAG Appliance

When you install an update for Microsoft Forefront UAG, it does not appear under the Windows control panel > Add/Remove programs. So, If you have to remove it for some reason then how do you remove an update? Well, UAG has an in-built script to remove the previously installed updates. The script is located at

nTMG: FTP Server Publishing in TMG

 

Open the Microsoft Threat Management Console and right click on the Firewall Policy and select "Non-web Server Protocol Publishing Rule". A new server publishing rule wizard will appear. Give a name for the publishing rule and click next.
