I'm new to web server configurations especially in IIS and was running the following page: http://schuynet.slulabservices.com/schuynet/ on IIS6 (Windows Server 2003). Since upgrading to IIS7.5 (Windows 2008R2) when trying to submit a form which posts to a file with a .dll extension (schuynet.dll?user) I get an error 405-HTTP verb used to access this page is not allowed.
I've done some research online which told me to do the following:
1. Ensure ISAP Filters and Extensions are installed components.
2. Ensure an exception is created for the specific .dll file in ISAP Filters and CGI Restrictions.
3. Change the extension of the file to .asp
All of which haven't worked and I am no closer to solving it. Can anyone help me figure this out? I would definitely be in your debt.
