>>If you are talking about IIS's FTP, you need to assign the rights in the Directory tab under IIS's Service Manager applet, and you need to assign the NT rights to the same file system directories. A user only has rights if both are set. If you are talking about the basic FTP (not IIS), I don't know this.

My later message is talking about NT permissions for the directory. I suspect your problem is there.

In the FTP service, the main thing to check is that you don't have the "allow only anonymous connections" checked in general, and that the specific directory has at least Read if not Write checked.
