followed by

You might not have permission to perform this task

I have used HVRemote tool to ensure all user and firewall permissions are ok, all the services have started correctly, I've even turned of the firewall to see if that helps, all to no avail. Any ideas?

Well I found the solution to the problem, it turns out accessing the hyper-v server using the IP address causes this, if you use the host name it works ok.

Open port 137 and 138 on the firewall on Hyper-V server ;-)

Manage FireWall on Hyper-V Server Core : netsh advfirewall set currentprofile settings remotemanagement enable

For change IP configuration :

Change IP Addresse : Netsh interface ipv4 set address name=LAN source=static address= mask= gateway=

Change IP DNS : Netsh interface ipv4 add dnsserver name="LAN" address= index=1

Show interfaces : Netsh interface ipv4 show interfaces

Show interfaces config : Netsh interface ipv4 show config

Rename Interface : netsh interface set interface name="Connexion au réseau local" newname=LAN

Disable network Interface : netsh interface set interface LAN disable

change Computer name : Netdom renamecomputer OldName /NewName:NewName
