Heya ladies, long time...

Huge issue I can't figure out. I have a PDC with IIS 4 running. I have 21 folders that I have seperate permissions for 21 seperate users. One user cannot get into anothers folder so anonymous is turned off. BUT, they try to login to the ftp server and its says <user> cannot login. They are all domain users. Now the catch, I'm a Domain Admin and I can login. If I give a user admin rights they can login but can also see all the other folders....
Any ideas??
