We have an IIS site running Dotnetnuke that we took over from another group. We have added a robots.txt file to the root but it returns a 404. Actually any txt file in the root seems to return 404.
I can't seem to spot where they may have blocked this. Any suggestions?
EDIT: We have a duplciate of the site files and database setup on a clean IIS server and it works fine there, so it seems to be at the IIS level or somethign else outside of the web.config or similar.
EDIT2: Turns out it was a bug within a module that the developer had been using causing redirects for txt files to be messed up. Thanks everyone that replied.
