IIRC, in order for a user to be able to log in to NT IIS FTP, they have to have log on local rights when anonymous access is disabled... We ran into this problem on our server a few months back. If I find that my answer was wrong or I can pull up what our solution was, I'll repost on here...
I seem to remember that we had to allow log on local and change something in the IIS FTP options... If log on local doesn't work, I'll dig up what we found.
