Ned here. If you have started having event 17 errors with your licensing servers for Terminal Servers / Remote Desktop Servers, go read the following immediately:

Event 17 – Certificate Corruption on Terminal Services/Remote Desktop License Servers  

There's an easy fix, you just need to know what to do. More news on this later.

Go. Go now. GO!
