Ok, here's the beef.
I have 1 Win2000 box running Active Directory and IIS5, with multiple web and ftp sites. I setup a FTP site for a friend. This FTP site will only allow a user under the administration group to login, but no one else. I have made an acct for my friend in Actice Directory and added him to the folder permissions for the FTP site. I have also disabled anonymouse access. Everything works perfect, just that he cannot login to his ftp site.
I checked the LOG files, and found
14:29:55 22.214.171.124 USER jamesd 331
14:29:55 126.96.36.199 PASS - 530
331 = User name okay, need password.
530 = Not logged in.
