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
http://blogs.msdn.com/rds/archive/2010/03/30/event-17-certificate-corruption-on-terminal-services-remote-desktop-license-servers.aspx  

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

Go. Go now. GO!
