In order for windows based auto-discovery tool to collect information from windows servers it needs to connect to remote machines using WMI/WinRM.
We have an older article that helps with some of the error messages: https://device42.zendesk.com/entries/27009367-D42AutoDisc-Client-Windows-or-Hyper-V-auto-discovery-error-messages

The WMI Diagnosis Utility
This is a utility to help system administrators diagnose and repair problems with the WMI service. Please run this to see if you can connect to the remote computer.
