How To Enable Integrated Windows Authentication in IIS 7

16 06 2010

I’m currently working on a website that was created in .NET 1.1 and Visual Studio 2003 and I had nothing but nightmares getting it to work on my Vista machine which is running IIS7! My final hurdle was getting it to run in Debug from Visual Studio 2003. To do this I needed to enable integrated Windows authentication for the website. So here is how I did it:

1 – Open IIS Manager

2 – Highlight your website that you want to enable integrated Windows authentication for


3 – Double-click the Authentication tab

4 – Where it says “Windows Authentication” in the Name column, the status column should read “Enabled”. If it reads disabled, right click and select “Enable”.


This did it for me and I was then able to go back into my Visual Studio 2003 environment and successfully run the website in debug mode. REMEMBER!!! Visual Studio 2003 might need to be run as an administrator to allow debugging (Right Click — Run as administrator) so if you are still having problems give that a go!
