Use Windows Authentication as the Login requirements of VS Web page instead of ASPNETDB.mdf

Hi,

I'm a newbie to VS, using VS 2010 Web and have created a web page which is linked to a SQL database which uses Windows authorisation. I set up the ASPNETDB standard login pages following the tutorials however I would like them to reference the users Windows login details rather than maintain two user/password lists.

What is the best way of doing this please?  Do I have to use an IIS or is there a way to link the ASPNETDB users to the Windows directory for authentication?

Thanks
