I created a new server and moved the links site from iis 6 to iis 7. The site seems to function fine in almost every way including builds and in dynamic cgi mode. However when a user try's to login to rate a link, add a link, or do anything it shows the login screen again. It doesn't throw an invalid login error just simple looks like it refreshes the login page. My guess is it's a rights issue since all the files are the same from the other server but looking for some insight.
