In order to connect to your computer from outside the institute, you can use a so-called remote desktop connection. This allows you to display your computer screen as if you were sitting in front of it at the institute.

You may first need to install a small program on your lab computer that will allow to show your screen elsewhere. Please ask the DSI to install a remote desktop server.

Sitting elsewhere, you will install a remote desktop client on your other computer (the one you want to physically sit in front of). You will then initiate a VPN connection to the institute, turn on your client, enter the ip address of your lab computer, and voilà!

Now in detail, here is how things should go like on your computer.
