SSO implemenation with ADFS 2.0 for sharepoint site

Hi ,

I need to implement SSO and by SSO i mean if users has loged into their PCs (desktop machines) and access the sharepoint site then they should not need to re-enter login credentials. this is what i wante to achieve. I have read this article:

http://social.technet.microsoft.com/wiki/contents/articles/10452.sharepoint-2010-how-to-install-and-configure-adfs-2-0-on-windows-server-2008-r2-for-sharepoint-2010.aspx

But not sure it will work in my case (no reentering the credentials after system login).

Any suggestion please?

Regards

Atiq
