Why won't the "Network Interfaces" properties open in Windows 2012?

Question

Windows Server

https://www.youtube.com/watch?v=Y-fqUMVNAy0 - I set up a server using this link, but got stuck in the place where you need to change the settings in the "Network interfaces" category.
Stupidly - the window does not come out. You press LMB twice, through RMB you go to the item "Properties" and through "Actions" also zero reaction ... how to fix it?
