Remote Disk Management

On the computer which you use to connect to the server core, run this command:
netsh advfirewall firewall set rule group="Remote Volume Management" new enable=yes

Or this powershell:
Enable-NetFirewallRule -name RVM-RPCSS-In-TCP,RVM-VDSLDR-In-TCP,RVM-VDS-In-TCP

….ON BOTH THE SOURCE AND TARGET MACHINES!!!
