Computers are added to the Computers table on the Carbon Black App Control Console when you install the agent on them and they contact the Carbon Black App Control Server – there is no special “Add Computer” operation required.

If you are using AD-based policy assignment, a new computer is assigned a policy based on the rules you set for mapping AD data for a computer (or its users) to security policies. Otherwise, the computer is assigned the policy specified in the agent installation package chosen for it.
