Remote Desktop Connection Internal Error has Occurred Fix
I recently had this issue when trying to RDP to a Windows 2012 server and here is how I resolved the issue.
1. Console to the server either by connecting a KVM to it if its physical or via the console session if using vMware and or Hyper-V
2. Browse to:
C:\ProgramData\Microsoft\Crypto\RSA
3. Rename the following folder
Machinekeys
to
Machinekeys_backup
4. Open services.msc and restart the "Remote desktop services" service <comments />
