probably permissions is the problem - i.e. IIS doesn't have the right to run a shell and/or the binary in question.
BUT who cares ... you shouldn't be using exec() in a script that's evoked via a webserver if you can really help it.
it seems you have a binary that takes a url and makes a visual snapshot of the resulting webpage as seen in IE, I
would suggest that you run a background task that regularly updates a cache of such images using the exec() technique
given above (maybe using a database as a source of urls to check) and then have you web scripts use the cached data
as needed.
otherwise your off into the dark woods of windows/IIS permissions (can't help you there I'm afraid)
