The problem is that when we are trying to install the Windows server 2012 R2 on our RH2288H V3 server.
The NICs unable to be enabled after OS installed.
Please follow the next steps:
1. Powered off Server (unplugged power cords)
2. Powered on server
3. Uninstalled drivers
4. Restarted server
5. Installed drivers from Jason
7. Installed latest drivers from Intel Site
Check the status again, and if you have the same situation, please replace the NIC.
