SetAccessSecurityDescriptor method of the Win32_DCOMApplicationSetting class

The SetAccessSecurityDescriptor method updates the access security descriptor of the DCOM application with a new security descriptor that is defined by an instance of a Win32_SecurityDescriptor class. This security descriptor controls who is allowed to access the application. The account running the script or application that calls this method must have the SeSecurityPrivilege and SeRestorePrivilege privileges. For more information, see Changing Access Security on Securable Objects.

Syntax

  [in]  Win32_SecurityDescriptor Descriptor
);

Remarks

The Win32_SecurityDescriptor instance represents a SECURITY_DESCRIPTOR_CONTROL data type and contains a discretionary access control list (DACL) and a system access control list (SACL). For more information, see Access Control Lists.

If the SeSecurityPrivilege is not granted or enabled when getting a security descriptor, then only the DACL is returned in the returned security descriptor. For more information, see Privilege Constants and Executing Privileged Operations.

You can update both the DACL and the SACL in the Win32_SecurityDescriptor instance when calling this method, but you also can update only the DACL or only the SACL.

The following values in the SECURITY_DESCRIPTOR_CONTROL determine whether the DACL, the SACL, or both are updated.

  • SE_DACL_PRESENT

    Indicates that the DACL should be updated. If this is not set, then WMI preserves the original value of the DACL.

  • SE_SACL_PRESENT

    Indicates that the SACL should be updated. If this is not set, then WMI preserves the original value of the SACL. To update the SACL, the account must have the SeSecurityPrivilege privilege enabled. For scripting, the privilege name is SeSecurityPrivilege. For more information, see Privilege Constants.

If the Group trustee and the Owner trustee properties are not NULL, then they are updated. Otherwise, WMI preserves the original values. For more information, see WMI Security Descriptor Objects.

When a new SACL is NULL in a call to this method, then the security descriptor SACL on the target securable object is left unchanged.
