As an employee of Iron Networks, a Microsoft OEM partner, I’ve had access to very early beta bits for Windows Server 2012 R2 and Windows 8.1. I’ve been testing DirectAccess for quite some time now, and while there haven’t been any real changes in features or functionality, Windows Server 2012 R2 does include many under-the-hood fixes that address some common issues that were present in Windows Server 2012. During all of my testing (performed weekly as we received new builds from Microsoft) I never encountered any issues. Surprisingly, when I first received the Release to Manufacturing (RTM) build, I discovered a pretty serious issue! You can read all the details here.
For organizations looking to take advantage of cloud-based services, often one of the first services to get migrated to the cloud is mail. However, for some companies this is not an acceptable alternative, typically due to regulatory or compliance reasons, but sometimes it’s a simple as not wanting to give up control of e-mail communications. For those that are sticking with on-premises Exchange and are migrating to or have deployed Exchange 2013, you can leverage Forefront TMG 2010 to provide secure remote access to on-premises Exchange 2013. Although not supported natively in TMG, you can still make it work. Read more here.
