Once again, I find myself mentioning tools that we have already taken the time to describe previously in this book, but with good reason. We have left the specifics of these commands in Chapter 3, Daily Tasks in Group Policy, where they belong, but they are worth another honorable mention because GPResult and RSOP data is often the key ingredient needed when determining a GPO filtering problem. Let's take a look at the output of each command for an idea of what helpful information is provided to us.
