DW 8.0 Issues with IIS7.0

I'm really struggling to find the answer to this one.

I've just changes hosting companies and now have a virtual private server running Windows web server 8.0 and IIS 7.0

I'm using Dreamweaver 8.0 and classic ASP.

The 'log in user' server behaviour doesn't work.

I set up a basic ASP page and applied this sever behavious to eliminate any other possible problem.

When i try to log in, the page doesn't do anything. I don't get any errors, nothing.

I set the redirect in this code to: If login correct go to google.com if login in-correct go to bbc.co.uk just to test it.

It work fine on my local machine IIS5 and my old hosting IIS6

Does anyone know why this is?

My e-commerce site uses code to add product to the shopping cart and this has the same problem.

I have a feeling that it has something to do with Request.Form or Request.QueryString but i'm not sure.

Thanks in advance
