WordPress multisite urls fails, WordPress seem to redirect incorrectly

Question

I am aware this question has been posted previously but the answers do not solve my problem.

when setting in wp_config file is like so:

define( 'PATH_CURRENT_SITE',  '/wordpress/' );

links to network admin (http://localhost/wordpress/wp-admin/network/) and main site (localhost/wordpress ) work but other sites fail, for example localhost/wordpress/anothersite

if I change setting in wp_config.php with an xtra forward slash like so

define( 'PATH_CURRENT_SITE',  '//wordpress/' );

only the link to network admin (http://localhost/wordpress/wp-admin/network/) fails but all site url work

I believe there is a problem with the web.config file but do not know how to configure it:
