How to enable a grayed out COM+ button on Win 2003

Case: on a Win 2003 server (not DC) it is impossible to enable COM+ because its button ("edit limits") is grayed out. How to enable it?

The referring security policy is: DCOM: Machine Access Restrictions in Security Descriptor Definition Language (SDDL) syntax, which can be found in: Local Security Settings\Security Settings\Local Policies\Security Options, and it must be set to "Not Defined" in order to have the button enabled.

On the (not DC) box, it seems to be impossible to set the policy to such value, and therefore the following registry key must be erased: HKLM\Software\Policies\Microsoft\Windows NT\DCOM.
