I not Brian (he's a jedi master, I'm a jedi apprentice)
But I'd bet I'm better at MS Exch 2003/2007!
There is a requirement in OSPF that traffic between any two non-zero area's
pass thru area 0 (the backbone). In your case I suspect another routing
protocol is running, or an interface is not in the area you think its in.
Please post configs so we can end this issue for you.
