URL Rewriting not working in IIS 6

Hi

I have done URL rewritting refering below article

http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx

I am using IIS 7.0 on my local machine and it is working fine but on my production it is IIS 6.0 and over there it was not working.

It gives HTTP 404 error when I click on any link.

I have done Url rewriiting like this

From This: Response.Redirect("Product.aspx?pid=" + ProductID) this works on both IIS 6 & 7

to this: Response.Redirect("Product.aspx/" + ProductID) this works only in IIS 7 not on IIS 6.

Please help how can I achieve above in IIS 6
