This has been a chronic problem for years - FTP is part of the DW web editor and should function flawlessly. I have tired every combination of FTP settings in the site manager's FTP options. I publish to multiple servers (CentOS Linux, and Windows) in different locations. I am stuck in DW (can't FTP) as I write this post; testing 3 different sites at three different hosting locations, I can't post to any via DW and have a waiting on server error and time out. Usually, I can cancel and try again and may FTP on subsequent attempts. I opened my backup FTP, Filezilla - - click and posted the entire site in a few seconds. All my sites were OK with Filezilla FTP but then I tried again in DW and I'm still stuck, It can work one moment and timeout the next and the problem is not on the servers or networks, its in DW.
Calling Adobe support, gets you to a level 1 person who is talking to several people at the same time, this is why a simple question takes 5 minutes and you are on hold for 4. When support gets tired of you, you get disconnected. When you have a ticket in the system, no one ever resolves it.; I have several tickets over sever years, each new version same problem, same call to Adobe. At MAX 2009, and MAX 2010, I addressed the issue with GR, Adobe Dreamweaver Evangelist and other DW presenters ... some were clueless and other like Greg said, "here is my card, email me and I will follow up" But never a reply ...
If you are reading this and have the same issue email or call some of the writers of the dream weaver bible books and other DW books - someone may have an in, or an Adobe contact at the DW ivory tower folks and let them know the problem or get a real answer - FTP is not rocket science and there is open source code that the brain trust could look at if they cant figure out how to FTP.
The Adobe DW Support, kindly post a response and a solution.
