I've since found that out. Too bad because it would make their Protected URL feature far more valueable. As for using Windows tools or scripting, it is my understanding Protected URLs are done within the Plesk system and not a Windows function. Regardless, the site is on a hosting server and I do not have the authority to make calls to the Windows security system (at least I don't believe they would offer me that option). For what it's worth, my hosting service support has placed a request with Plesk to offer this feature in later versions. Perhaps - someday...
