Hmm, I would certainly try moving it and see if life improves. I've
noticed Windows do strange things to files created by Rabbit / Erlang,
but then again, I've noticed Windows do strange things.

You should be able to set the environment variable RABBITMQ_MNESIA_BASE
to the directory you want to use. When Rabbit starts up, it will display
this directory just under the banner so it should be pretty easy to
check if it's taken effect.
