I am trying to UNC Path to the C drive of a hyper-v based VM that is running Windows Server 2008 R2 standard.
I can RDP into the system just fine using the machine name.
When I enter the UNC path: \\machinename\c$
I am prompted for credentials.
The server is not a part of the domain so I enter the login as such machinename\Admin
and enter the password. The authentication fails.
When I go to event viewer and look at the security logs I see many failed authentication attempts with my username from my domain. Why would this occur? Why would it submit my domain credentials despite the fact that I logged in with an entirely different username and password?
I have never tried to log into this machine using my domain credentials.
Edit: Worth noting that I can UNC into a shared directory on this system, just not the C drive.
