I have Active Directory 2003 and my users are on Windows XP. How can I set a policy to active network configuration for the users? In other words some users are traveling a lot so I want to give them allow to change network configuration.
You can manage the network configuration on a system without having local Administrator rights if you are a member of the "Network Configuration Operators" local group; so you will need to add your domain users to this local group on the machines where they need this specific right.
Whatever is better to do this via group policy or manually depends on if you want those users to have this right on every computer or only on their own one.
