First hint: use <c>...</c> around code (update : which was not the case as initially posted. </update>)
Second, et seq: There's nothing in the script you showed to explain this commonplace problem.
So, (granting that some/all may be irrelevant under IIS) is the script executable under IIS6; is it in the right place (/me suspects the hashbang gives a path that's incorrect from the server's perspective); does the server have permissions to execute anywhere in c:\strawberry\perl\bin\ and, specifically, in whatever dir your script is stored? Is the server actually running ("The requested site is either unavailable or cannot be found.") and last, but definitely not least, what gives you the impression "it seems like it is trying to be downloaded to my browser...?"
