I haven't been ignoring your suggestion, Charles, I just wasn't clear in my own mind how I would apply it. Michael's message helped clear the fog. One thing about this hobby---you never run out of things to do. Regards, Kent PS to Michael: Funny about 'Igor.' The same connection flashed through my mind.

Never knew anyone named Igor, so there you are. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
