My Windows Server 2012 is missing disk space. I'm completely lost here, have no clue where the other 20 GBs have gone.
Could anyone assist me?

Firstly I would check that the file system isn't corrupt as you could run into all sorts of issues. Please try using chkdsk (Windows built in disk checking tool) to check:
Open a command prompt as administrator
Type chkdsk C: /F and press Enter
It may well inform you that it cannot lock the volume and requires a scheduled check at boot time, in which case enter Y and press Enter. You'll need the server/VM to be rebooted for the check to go ahead and obviously there will be some down-time.
If this doesn't work you could try the procedure below. I would recommend getting a full backup done beforehand though
Open a command prompt as administrator
Type diskpart and press Enter. A new command-prompt should appear.
At the DISKPART> prompt, type list volume and press Enter. This will show all the volumes on the system
Type select volume # (where # is the number of the relevant volume) and press Enter
Type extend filesystem and and press Enter
This should adjust the filesystem to use all available capacity in the volume and is based on several articles on the web, including this KB article.
If that still doesn't work, you could try repeating the above but use extend instead of extend filesystem as this will extend the volume itself if there is unallocated space on the disk. But I don't think that is the issue.
Lenovo installs a pretty useful application called "Rescue and Recovery" on most of it's systems. This applications performs full scheduled backups of your system to your hard drive, which you can access on boot by pressing the "ThinkVantage" quick-key on your keyboard.
Most probably the used space that windows is reporting incorrectly is the hidden portion of the disk that Lenovo's software is using up.
Search for Rescue and Recovery in "C:\Program Files\Lenovo\Rescue and Recovery" and start up the application to check for the backup regime that's running.
You SHOULD also be able to access the software from the Control Panel under "Lenovo's Enhanced Backup and Restore".
