ER Errors Reported

Running a computer discovery against a list of servers, i receive a number of errors. There is lack of explanation as to what they may be. There is nothing in the knowledge base that explains the root cause. Here are a list of errors i need to understand then resolve. LOTS of the servers in the list reporting these errors. Not all the same errors for each machine.

I replaced actual server name with <servername>
