Are you using FM Server or FM Server Advanced?
I believe you need Advanced for IWP to work.
Thanks for the response. We are running Server Advanced. Sorry for not mentioning that in my last post.
From doing a little research it seems like this is a problem with IIS not pushing the right MIME type for the Filemaker web page, so a client's browser sees "iwp" as an unknown file type & tries to download it. Wierd.
I tried adding MIME types to the IIS server configuration, but that doesn't seem to solve the problem.
This is the first time I'm using a Windows based server for Filemaker. For my taste, seems like IIS is not as user-friendly as Apache.
