I have little problem with this. The networking does not work. I have installed Windows server 2008 r2 in my MBP 2014. This involve converting 'install.esd' to 'install.wim' and integrating drivers derived from respective Boot camp version, and convert back to 'install.esd' and replace in the bootable USB - sources folder. Then installation was cool. The missing drivers can be installed from Boot camp drivers folder. After all these, the networking does not work. I noticed that the driver got installed, and the driver for 'intel (R) 8 series lpc controller' is not installed. Already, I integrated this driver with 'install.esd'. As I noticed from release notes, the driver should be installed prior to OS installation for 'Windows Server 2008 r2'. I tried this while installing. I could not succeed. Could any one share their experience?
