When installing the protection on a computer using the installer, you must select the group that the computer will be added to once the installation is complete.
Groups can be manual or automatic (arranged by the IP addresses of the computers that comprise them), and they can contain subgroups. In the case of the automatic groups/subgroups, the computers that make them must meet a series of rules based on their IP addresses. These rules are configured when creating the group/subgroup.
There are two ways to add a computer to a group/subgroup depending on whether the group/subgroup is manual or automatic.
In the case of manual groups there are no problems, any computer can be added to a manual group/subgroup. However, if the computer is to be added to an automatic group/subgroup, it must meet the rules specified for it.
If the computer does not meet the rules of a subgroup but does meet those of its parent group, it will be moved to the group whose rules it does meet.
