We have been asked more than once for documentation on the RDP protocol, UDP transport, RD Gateway protocol, etc. So we have put a list together of this kind of documentation. RDP Protocol Specifications are at MSDN. Go to the  MSDN Library > Open Specifications >. Then go to navigate to Protocols > Windows Protocols > Technical Documents> The RDP specs are way down in that list under [MS-RDP…] [MS-RDPADRV]: Remote Desktop Protocol: Audio Level and Drive Letter Persistence Virtual Channel Extension [MS-RDPBCGR]: Remote Desktop Protocol: Basic Connectivity and Graphics Remoting [MS-RDPCR2]: Remote Desktop Protocol: Composited Remoting V2 [MS-RDPEA]: Remote [...]

For those interested in learning how much it might cost you to move your Azure RemoteApp deployment or your on premises RDS deployment to XenApp and XenDesktop on Azure, here's a cost calculator to get you started. https://costcalculator.azurewebsites.net/costCalculator This tool takes two paths: Extend your current Citrix deployment into Azure, or move to Azure and let the new Citrix Cloud Service do the heavy lifting (more on Citrix Cloud here).  

Glad to say that the October 2016 Monthly Rollup contains a hotfix for the present User Profile Disk dismount issues some of us have been experiencing (and complaining about). October 2016 Preview of Monthly Quality Rollup for Windows 8.1 and Windows Server 2012 R2 Addresses issue where the user profile disk (UPD) does not dismount when a user logs off. Therefore, users get temporary profiles and are not able to work with their own profiles during their next logon. The Event ID 20491 with a description of “Remote Desktop Services could not disconnect a user disk for the user account [...]

Benny Tritsch's Ignite session is now available here! This session highlights Microsoft Windows Server 2016 Remote Desktop Services from the perspective of an independent subject matter expert. Join Benny Tritsch as he shares his experience from real-world RDS projects and his thoughts about the potential Windows Server 2016 has for your desktop virtualization and session remoting use cases. Get in-depth information on how good the RDS 2016 end-user experience is and learn how to measure it yourself, both on-premises and on Microsoft Azure. Other important topics discussed in this session are RDS 2016 management concepts (administrator experience) and the known [...]

Microsoft is busy at work pushing out some new documentation on RDS deployment and upgrading in Windows 2016 (and much of it is instruction for Azure deployments).  Here is starting point: Deploy a basic desktop hosting environment using Azure IaaS Deploy a Storage Spaces Direct scale-out file server for UPD storage in Azure Upgrade your RDS deployment to Windows Server 2016. Configure your desktop hosting environment. Deploy a desktop hosting environment. Deploy a Remote Desktop Session Host farm to improve availability. Deploy a Remote Desktop Connection Broker cluster. Deploy a RD Web Access and Gateway farm. Deploy RemoteApp programs. Deploy [...]

At a client we noticed that after our last round of patching the RD Web Access web feed broke.  All of our servers run 2012 R2.  The broken feed was evident on Windows 8.1 and 10 PCs/laptops that connected using RemoteApp and Desktop Connection and also on iPads (makes sense because these all use the feed). Removing KB3098785 fixed this for us (Security Update for Microsoft .NET Framework 4.6) Note: Our RD Web Access server is also running RD Gateway. I have not tested whether the RD Web Access feed breaks on a server with only RD Web Access installed.

I have observed the RD Gateway Manager console crash specifically when you go to add a CAP or RAP policy.  For me, the .NET Framework 4.6.1 update KB3102467 was to blame. Here's the fix. https://support.microsoft.com/en-us/kb/3162871
