Remote Desktop Gateway SSL Error, or Network Access Protection LIES!!!

Your computer can’t connect to the remote computer because your computer or device did not pass the Network Access Protection requirements set by your administrator.

Had an email from a friend today, who had an Essentials 2012 R2 Server with a problem when trying to use the Remote Desktop feature of RWA. They were presented with this warning message,

A bit more background, was that the Servers SSL Certificate had expired and been replaced. Since then RDP via RWA failed.

We reviewed the Dashboard.log and found the following:

[10688] 150120.175533.4464: RDP: RDS-Gateway is installed
[10688] 150120.175533.4464: ConnectivityCenter: TsGatewayInfo.TsGatewayConfigured: False

[7740] 150120.175533.5695: ConnectivityCenter: Suggestion: There is an issue with your Remote Desktop Services settings that cannot be automatically repaired. Please contact Product Support.
[7740] 150120.175533.5695: ConnectivityCenter: Overall status: Error

Running the Anywhere Access wizard to attempt a repair, also failed.

The solution was quite straight forward, and i actually covered the process back with SBS 2011 Essentials here.

The look of  the console will of course be slightly different, as the example there is from Server 2008 R2, however the steps are pretty much identical. Once you have repaired the RDP Gateway SSL, you should be back in business.
