The SDProp option provides the ability to report which accounts are protected by the SDProp\AdminSDHolder process. It will show which group or group inheritance has resulted in the user account being included and which accounts have been orphaned by the process. Some details on the process can be found here and here.
NetTools will display the user objects that have the AdminCount set to 1 and associated group memberships that triggered the user to be covered by the process. The group membership of the account is shown horizontally, if the account is a member of multiple protected groups subsequent group memberships are shown on the next line, as is the case with the adm-test-ad user below. This option also provides the ability to reset user accounts, by enabling ACL inheritance and clearing the AdminCount attribute. To reset all accounts, select the Reset AdminCount & ACL Inheritance option and clicking Go or by using the Reset ACL & AdminCount option from the context menu to reset one or more selected accounts.
One of the features\issues with the SDProp process is when a user is removed from a protected group the SDProp process will not longer control the SD, the process doesn't re-enable SD inheritance and as such the account is classed as orphaned. In the screenshot above is shows two users user1 and user2, this shows that User1 is a member of Domain Admins and Administrators, and as such the account will have the AdminSDHolder permissions enforced when the SDProp process is run, User2 on the other hand is not a member of any protected groups and the AdminSDHolder permissions will no longer be applied and it is now orphaned.
Once the permissions have been reset, it is possible to trigger the SDProp process to run by clicking on the SDProp button. This will query which domain controller holds the PDC role and sent the runProtectAdminGroupTask command to that DC. Below is a LDAP Search favorite Update Query that is used to trigger the SDProp process, if run against the PDC of the domain, this uses the RunProtectAdminGroupsTask RootDSE Modify Operation.
