I have installed Hyper-v R2 core system in a workgroup configuration. I added a user with matching credentials of my laptop for username and password. I am able to connect to the Hyper-v from the Hyper-V Manager on my laptop just find but when i try to create or edit vhd i receive the follow error which i attached a screen shot of. I can not seem to figure out what is wrong as i believe the user account is a member of administrators on the local machine (hyper-v machine).
I thought it was a possible firewall problem so i disabled the firewall on the Hyper-v server and that did not resolve the issue.
