DHCP Admin Group in Server 2012

DHCP Admin Group in Server 2012

The DHCP admin group is a Windows security group used to provide DHCP admin access to users who need to perform DHCP admin function in their work role(s). The sister group, DHCP Users provides read only membership to see DHCP information.

In Server 2012, Microsoft disabled the DHCP users group and hid it from view. This can be a bit frustrating if you need to use this group! The reason I believe was that Microsoft considered this to be a more secure arrangement.

Re establishing the DHCP Admin and DHCP user groups is rather simple. On the Server, open an administrative command prompt and enter: netsh dhcp add securitygroups then press enter. This will add both groups to your group management console (you may need to refresh to see them)

Grant Sudo Access in Ubuntu

To make changes in Ubuntu, you need to be a member of the "Super Users" or Sudo group. Membership of this group acts like the administrator group on a windows system, allowing users to make changes to the operating system. Ubuntu will prompt you for the sudo password (which is recommended to be different to your normal user password for security reasons) when you attempt to make changes to the OS.

To grant a user sudo access:

1. log in with your own sudo level access account
2. enter the command sudo adduser sudo
