Windows Server 2012 and 2012 R2 Internet Download Speed Slow

Problem:
On a fresh installation of Windows Server 2012 or 2012 R2 and latest LAN drivers, internet download speeds and browsing are very very slow.

Solution:
Run the following in the cmd window:
netsh interface tcp set global ecncapability = disabled
