What the best way to monitor Windows?

That's exactly what I do.  I have a medium sized environment with 200+
Windows servers to manage.  I have NSclient++ on every windows host, using a
CNAME "monitor" and have a NSC.ini already configured and dropped into
place.  Works like a charm.  With this method, I can also have check_nt, and
check_nrpe if needed.
