I tried to install windows server 2012 on a desktop for training purpose.
I made it a DC and gave the following IP address
But when we connect to the switch, I could not ping to other laptops and the laptops cannot ping to the server. I have turned off all firewall.
The network gave limited connectivity. I have uninstalled the driver and reinstall, tried windows update to find the latest driver.
I need the AD server to be able to connect and ping to other laptops. Anyone can give me some important information to make it connect.
