If AD RMS was already installed before, uninstall it to provide a more secure, hardware-based cryptographic service provider for the RMS cluster key in further installations. For this purpose, complete the following steps:
-
Open Server Manager (Start → Administrative Tools → Server Manager).
-
Start the Remove Roles Wizard (Roles → Remove Roles) and click NEXT.
-
Unselect the roles Active Directory Rights Management Services and Internet Information Services and click NEXT.
-
Click REMOVE.
-
Reboot the machine as soon as the wizard is done.
-
After login, wait until the installation is complete.
-
AD RMS clients use a service connection point (SCP) to automatically discover the AD RMS Custer. To unregister the old SCP, download the RMS Administration Toolkit with SP2 and install it.
-
Open a command prompt (Start → Run → type in
cmd), navigate to the installation folder:-
cd C:\Program Files\RMA SP2 Administration Toolkit\ADScpRegister\ and unregister SCP:
-
ADScpRegister.exe unregisterscp.
