You might be better not running the routing protocol on the Windows box,
and run gated (or whatever) on some nearby Linux/BSD box which tests the
availability of each of your windows box and introduces the appropriate
route (i.e. a next-hop for the anycast address pointing at a normal IP
address) into (a very local) BGP (running multipath) or other favorite
routing protocol for each of the servers that are up.
