Here at Liquidstate, we have a home server running Windows 8.  It might seem like a simple thing, but today I drew a blank when trying to restart the server remotely from a Remote Desktop Connection (RDP).  If you try the normal routes, then the only option available to you is "Disconnect".

The solution turned out to be remarkably simple:  go to the desktop and press Alt+F4.

You will then be presented with options to:

• Disconnect
• Sign Out
• Shutdown
• Restart

Hopefully that helps someone else!
