Helicon on IIS6 and Wordpress

Question

Hello all,

I have a site running on IIS6, Windows 2003, with Helicon (free) to rewrite urls.

I installed wordpress into its separate website under IIS

I can reach to the mainpage blog.domain.com/blog but when I try to click on the "Login" and type my username and password and click submit it will just 404 not found instead of redirecting to the wp-admin screen.

If i would type the exact url like blog.domain.com/blog/wp-admin/index.php to get into the admin panel

same happens sometimes for the pages or categories.

is there a way i can keep this site separate from helicon ; without disturbing the current helicon configuration ?

many thanks

ps : i have removed the http before the links to allow me to post
