Hi !
After installing Hamachi on my Windows Server 2012 R2 AND rebooting the server, the Internet access is broken.
The LAN is still functionning; the client desktops can access resources on the server.
But that's all: I can't access the Internet from the server itself (no ping, no surf).
If I disable the Hamachi network card on the server, I can access the Internet again but of course Hamachi is not available anymore. 
Any idea?
Nicolas
