Opanda IEXIF is Windows freeware and is often mentioned as being able to read Nikon D200 files. Just make sure to read a file that has not been edited so much that the original EXIF information has been altered.
I just realized this is an old thread. Well anyway... Flickr also displays the shutter count in its EXIF reader, if you're allergic to installing new software for whatever reason.
