The computer in your office on campus (call it the ‘server’) must be connected to the network via Ethernet. You cannot remote into a machine on the WIFI.
On the server:
(a) go to: Settings – System – Remote Desktop and enable remote desktop. (This option is only available on Pro and Enterprise versions of Windows, not the Home versions.)
(b) select the users that can access the machine under Settings – System – Remote Desktop – Users. Note the syntax for the account. You will need to use the same syntax when logging in, for example: KIEWIT\NetID
(c) Take note of the server’s name under Settings – System – About. It should be something like ‘UNIQUENAME.kiewit.dartmouth.edu’.
On the remote machine:
(a) login to the Global Protect Dartmouth VPN and then launch the Remote Desktop Application.
(b) in the computer field, enter the name of the server, for example “UNIQUENAME.kiewit.dartmouth.edu”
(c) you will be asked for credentials to login, enter them exactly as given in Settings on the server, ex. KIEWIT\NetID
(d) you may be prompted about the server’s security certificate, you can choose ‘yes’ to continue connecting.
