Fix network on Windows

Edit: this is not required anymore, MTU should be set to 1500.

If you are installing a Windows operating system on Luna Node Dynamic (note that you will require your own license), then you may notice strange network performance with packets dropping when large amounts of data are being transferred. This is because Windows ignores the MTU setting from DCHP server. To resolve this, you need to set the MTU on each network interface to 1450 instead of the default 1500.

To do this, you can follow the guide at http://www.richard-slater.co.uk/archives/2009/10/23/change-your-mtu-under-vista-windows-7-or-windows-8/
