When you try and install a role into server 2012 you get the following error.
Server name IP Online- Cannot get role and feature data
This is down to the user you are using to install the role not having rights to get the feature data while installing the role remotely. We need to give these rights with the command below. Replace the user account with the account name you need to give rights to, I’m using Allen here
Enable-ServerManagerStandardUserRemoting allen
You will now be able to install the role remotely.
