I believe it was Mark who has used this quote a handful of times and lamented not having an exact reference. I can't confirm this, but I found a PDF online[1] which sources it as follows:

"When things go wrong in your command, start searching for the reason in increasingly larger concentric circles around your own desk." Gen Clarke, [i]Reflections[/i], p. 17

In the vernacular, YOU ROCK!! Many thanks. It's a phrase I have used a thousand times, and regret the lack of cite every time.

I owe you one.
