When you try to get IIS web site (ASP.NET) to prompt for a download of a Microsoft Access .MDB file but the web keeps sending a “This type of page is not served” error

Server Error in ‘/test/manuals’ Application.
This type of page is not served.
Description: The type of page you have requested is not served because it has been explicitly forbidden. The extension ‘.mdb’ may be incorrect. Please review the URL below and make sure that it is spelled correctly.


The issue is with ISAPI extensions. IIS 6.0 is trying to execute the .mdb file rather than just download it.

Stop IIS, and right click on the Default Web Site and select Properties.

Select the “Home Directory” tab, and select “Configuration” option.

Under ‘Mappings’ tab, you will see a list of ISAPI extensions. If .mdb is selected in there, Remove it. Apply and Restart IIS.

  1. Great Post!
    It worked!

  2. Didn’t work for me … does it behave differently when the web server is on the local machine? Also, does the browser employed make any difference? Thx!

  3. Also, I just realized that I’m still running IIS 5.1 – I don’t imagine that this fix works for older versions of IIS as well?

  4. Simple and effective! Thank you!

  5. work perfectly!!!!

  6. Worked! Excellent. Thank you so very much!
