Windows XP : RDP via TS Web “error occurred… Desktop Gateway server.”

So user wants to connect to Windows Server 2012 essentials server via RDP, she had a Windows XP PC and the following error is being presented:

“An error occurred while sending data to the Remote Desktop Gateway server. The server is temporarily unavailable or a network connection is down. Try again later, or contact your network administrator for assistance.”

Turns out that this is a error with the newer RDP 7.0 client and CredSPP, there is a nice Fix IT utility from Microsoft, run it, reboot and the issue goes away. 🙂
