Some useful notes on the expanded options in the Management Center version 8.6 under Deployment Group (name) --> Settings.
Typically, machines become members of a deployment group according to the membership rules. However, the first two of these options allow the user to bypass the membership rules:
“Allow CCA to self-register with this group” is an old option that’s been in the product for some years. When enabled, machines can join a deployment group either from an argument passed to the installer, or by using the CCA command line tool “CcaCmd.exe /URL <URL> [<GROUP>]”.
“Allow CCA to unregister from this group” builds on the above option and allows the CCA command line tool to automatically unregister the machine using “CcaCmd.exe /UNREGISTER”. When called, the machine will be completely removed from the Management Server’s database.
“Allow CCA to initiate updates of agents and configurations” is again an option for use by the CCA command line tool. You can issue either “CcaCmd.exe /UPDATEAGENTS” or “CcaCmd.exe /UPDATECONFIGURATIONS” to install agents or configurations immediately. These options bypass the installation schedule.
All of these options require you to be a member of the local administrators group of the machine with the CCA installed.
