Window ftp login

I logged into my company ftp and checked the save password. Well, now I have to log onto a different ftp server within the same company but has different password. I can't get to the logon screen cause it automatically log in for me. How can I get to that login screen again to log to different server.

If this even makes sense. My IT guys aren't all that bright.
thanks

clear cache and cookies, and clear all saved passwords.

What FTP client are you using ?

Try using SmartFTP or FlashFXP or even FireFTP (if you use Firefox).
