Presumably, it uses whichever DNS server the local OS thinks it
should use, no differently than any other application on the machine.
So, the workaround for Dave who wants to block connections is simple,
for a given value of simple of course --  run a local, caching only
DNS resolver, which proxies everything back to the usual DNS server,
*except* for which Microsoft sub-domains you'd like to overrule.

I know nothing of BIND configuration (or any other DNS server) but I
imagine this is at least possible.

Unless the DNS server is itself hardcoded in MediaPlayer, as well?
