AOL requires a nonstandard method of entering FTP information. As of this writing, this is how AOL recommends entering Web-server information:

Launch Dreamweaver.
Launch AOL.
Sign on to AOL with the AOL software.
In Dreamweaver's Document window, choose Site > Define Sites to open the Define Sites dialog box.
Select the site.
Click Edit.
Switch the Category to Web Server Info to open the Site
Definition dialog box:

FTP Host is members.aol.com.
Host Directory is left blank.
Login is ftp.
Password is the user's full e-mail address (user@aol.com).
Note: You must log in to AOL and keep their software running in order to transfer to their FTP servers.
