I want to integrate YAF in my website. My website is in ASP.net and C#.net using SQL Server 2005 as backend.
I want to know, where the data related to forum posting, user registration etc. will be stored (i.e. My server or YAF server)

as i want the data to be stored on my server only. Do we have a solution for this?

Should be no problem you can use the same Server and Database for your ASP.Net Website and YAF. And also the same user data if you site uses the standard asp.net membership.

There is a Sample ASP.NET Demo Application available on the CodePlex Documentation Page  which is a standard ASP.Net Site with YAF integrated.
