Here is the history: I've been using Fling for several years to automatically upload files to my web site. It has been extremely reliable. I have not changed anything on the primary computer which uses it; neither hardware or software. Lately, the problem occurs where the ftp uploading fails because Fling is unable to access the target. I know it's not the password, because it works intermittently. I am using Windows7 and so far the problem has been seen to occur on every computer I've tried on my home network(4 out of 5). I called a friend in another state and asked him to try to access my ftp target using the basic Windows procedure which begins by right clicking on computer and selecting add network location. It's very simple to do. He was repeatedly able to log on. Using the same procedure, I am intermittently able to log on. I am unable to access even the anonymous ftp folder on my website. I have set up an location for ftp.mozilla.org and this works without fail. I have no problems logging on the the website using CPanel. I tried creating a new ftp account, but no luck with accessing that either. No problems pinging the ftp url. Here's where I'm at. Since I can access a public ftp location without issue and I'm having the same problem on all my home network machines, I'm ruling out the problem being local. Since my friend had no problems with the access, and everything else about the website is normal, I'm ruling out the web server itself. What can it be?
