The AGPM Server tab on the Change Control pane enables you to select an AGPM Server by entering a fully-qualified computer name and port. The default port for Advanced Group Policy Management (AGPM) is port 4600.
The AGPM Server selected determines which archive is displayed for you on the Contents tab and to which location the Domain Delegation settings are applied.
If the AGPM Server connection is centrally configured using Administrative template settings, the options on this tab are unavailable. For more information, see Configure the AGPM Server Connection.
