I have some computer that the agent is dying on. They work fine, then they just quit. You can still remote control, but not policies, bundles or anything else will work. I ran zac cc and then tried to register it and reregister it. On the registration I get the following error...

"Unable to register with the server at: https://myserver Unexpected server results. Server code: -34. Device Authentication Information."

Could someone steer me in the direction I need to go. It seems like I am losing machines by the hour. I have 4 right now. All four of these worked 3 hours ago. I have rebooted the server several times. Any help would be appreciated.
