I have a website that just has a standard index.html file in it for its homepage which works fine. In the same folder i have an executable file called ams.exe. if i type the url to my home page it works fine.
if i type the url with a /ams.exe i get page not found. i tested putting a plain txt file in there and if i type url to my site with /test.txt it works fine. it seems like its just .exe files.
When i set up the website it was done with all default settings and the evryone group has full permissions to the .exe file
I have tested it with a server running iis 6 and it all works fine.
