Windows Server: Where's the drive mapping?

Needed to map a drive on Server 2012 R2 to load some media so:

Start - right click "This PC" - check "Map network drive"

Than map to G: e.g.

Into command prompt with run as administrator set - type "G:" - no such drive - WTF? - I can see the mapping in File Explorer!

Turns out you have to do an extra step i.e.

net use g: \\"mapping path" password /user:domain\user /p:no

where:
g: = drive to map
mapping path = path to media
password = your password
/user:domain\user = your domain and user
/p:no = don't persist mapping across logins

Job done.

I suspect this will work on Windows 8 as well.

Enjoy!
