DeviceLock Consoles and Tools : DeviceLock Group Policy Manager : Using Resultant Set of Policy (RSoP)
  
Using Resultant Set of Policy (RSoP)
DeviceLock supports Resultant Set of Policy so you can use the standard Windows snap-in to view the DeviceLock policy currently being applied, as well as to predict what policy would be applied to a chosen computer.
To use RSoP, you should start MMC and add the Resultant Set of Policy snap-in manually:
1. Run mmc from the command line or use the Run menu to execute this command.
2. On the File menu, click Add/Remove snap-in.
3. In the dialog box that appears, select the Resultant Set of Policy snap-in, and then click the Add button.
4. Click OK to close the Add or Remove Snap-ins dialog box.
5. In the console tree, right-click Resultant Set of Policy, and then click Generate RSoP Data on the shortcut menu.
6. Go through the wizard that appears to collect the necessary data and build the resultant set of policy.
7. Expand the Resultant Set of Policy node in the console tree, and select DeviceLock under Computer Configuration.
Note that using RSoP you cannot modify the policy - all parameters are in the read-only mode.
RSoP is very useful when you need to understand which particular GPO will be applied to the computer.
