You need to remove Marc’s delegated rights. What would you recommend?
A.
Use the Delegation of Control Wizard.
B.
Run the Resultant Set of Policy (RSoP) tool.
C.
Run the dsacls command-line utility.
D.
Run the xcalcs command-line utility.
Explanation:
http ://support.microsoft.com/kb/281146
DSACLS is used to View or Edit ACLs (access control entries) for objects in Active Directory.
Overview of Dsacls.exe
DsAcls uses the following syntax:
dsacls object [/a] [/d {user | group}:permissions […]] [/g {user | group}:permissions […]] [/i:{p | s |
t}] [/n] [/p:{y | n}]
[/r {user | group} […]] [/s [/t]]
You can use the following parameters with Dsacls.exe:
object: This is the path to the directory services object on which to display or change the ACLs. This
path must be a distinguished name (also known as RFC 1779 or x.500 format). For example:
CN=Someone,OU=Software,OU=Engineering,DC=Microsoft,DC=Com
To specify a server, add \\Servername\ before the object. For example:
\\MyServer\CN=Someone,OU=Software,OU=Engineering,DC=Microsoft,DC=Com
When you run the dsacls command with only the object parameter (dsacls object), the security
information about the object is displayed.
/a : Use this parameter to display the ownership and auditing information with the permissions. /d
{user | group}:permissions: Use this parameter to deny specified permissions to a user or group.
User must use either user@domain or domain\user format, and group must use either
group@domain or domain\group format. You can specify more than one user or group in a
command. For more information about the correct syntax to use for permissions, see the
<Permissions> Syntax section later in this article./g {user | group}:permissions: Use this parameter to grant specified permissions to a user or group.
User must use either user@domain or domain\user format, and group must use either
group@domain or domain \group format. You can specify more than one user or group in a
command. For more information about the correct syntax to use for permissions, see the
<Permissions> Syntax section later in this article.
/i:{p | s | t} : Use this parameter to specify one of the following inheritance flags:
p: Use this option to propagate inheritable permissions one level only.
s: Use this option to propagate inheritable permissions to subobjects only.
t: Use this option to propagate inheritable permissions to this object and subobjects.
/n : Use this parameter to replace the current access on the object, instead of editing it.
/p:{y | n}: This parameter determines whether the object can inherit permissions from its parent
objects. If you omit this parameter, the inheritance properties of the object are not changed. Use
this parameter to mark the object as protected (y = yes) or not protected (n = no).
Note This parameter changes a property of the object, not of an Access Control Entry (ACE). To
determine whether an ACE is inheritable, use the /I parameter.
/r {user | group}: Use this parameter to remove all permissions for the specified user or group. You
can specify more than one user or group in a command. User must use either user@domain or
domain\user format, and group must use either group@domain or domain\group format.
/s: Use this parameter to restore the security on the object to the default security for that object
class, as defined in the Active Directory schema.
/t : Use this parameter to restore the security on the tree of objects to the default for each object
class. This switch is valid only when you also use the /s parameter.
