Hence the reason why I want the route to cease being advertised if the box
Connect the server(s) to APC MasterSwitch or equivalent hardware. Monitor the server box(es) for responsiveness. If/when it fails, the monitoring station can instruct the MasterSwitch to reboot (power cycle, really) the box. Stuff is pretty inexpensive (certainly less so than load balancers).

I'm trying to avoid putting yet another server load balancer box in front
of the windows box to withdraw the route so a different "working" box will
be closest.  It may be an oxymoron, but I'm trying to make the windows
service (if not a particular windows box) as "reliable" as possible
without introducing more boxes than necessary.
My initial thought last night was in fact the use of load balancers. But then you need to think about redundant load balancers and so on.
