I did stumble on another page on something that has worked for us.
1) STOP the Cryptographic Services service either in command prompt (run as administrator) or in services.msc It may take a few minutes for the service to finally stop. It may also, stop, but restart on it's own again requiring you to stop it again.
2) DELETE or RENAME the catroot2 directory located in C:\Windows\System32
3) Restart the Cryptographic services service.
I honestly don't know why this works, I found it on another forum and it has helped me out as we've had this issue on over 50 different machines in our office at various times. We have wondered it is all just Windows or if it is Windows conflicting with Carbon Black or Syxsense -- we just don't know.
