First of all you need to disable public login, you can do it by editing config file of the FTP server you are using.
Secondly , about GUI in windows, actually most of the ftp client are configured in such a way that if you only provide hostname then they connect anonymously first and because its enable in your ftp server so its is able to get in without authentication.

Hope this is what you asked for.
Also most of the time you create a user on linux and it automatically get capability to log in via ftp also.

well.. what exactly do u mean by GUI , are u GUI ftp client or u directly accessing from a browswer itself ?

Try "FileZilla" for doing ftp stuff from windows.

Hi

If u r trying to use from a Browser ..

Then use this:

ftp://username@ipaddress

means suppose your username is student
and ipaddress of ftpserver is 192.168.8.16

then type this is in browser:

ftp://student@192.168.8.16

After that it will definitly ask for username and the password

I think this is the thing u were asking about ..if i am not wrong.....

Enjoy:

Gaurav
