It means that the data that was received by the remote agent contained invalid data based on the protocol specs, this could be due to a network issue

Here is what it shows in the log: Thursday, August 21, 2014 1:54:55 PM External COM check (,34):ERROR: Invalid data received from remote server. Protocol error. Thursday, August 21, 2014 1:55:09 PM Remote Agent check (2,32):ERROR: Invalid data received from remote server. Protocol error. I’m not sure if I have something configured improperly or if something else would be causing this but it usually comes back up on the second or third cycle (I have it check every 5 minutes).
