I've seen this over the years time and time again but no one has a clear solution. I can ftp no problem but cannot publish without getting a "server does not exist" port 80 error. I've tried everything in existence including reinstalling FP to different computers and different operating systems, installing reinstalling frontpage extensions, turning off/uninstalling firewall, calling my provider to see if 80 was blocked, my webhost...no help...MS says it could be anything. I am testing a simple 1 page website that will sometimes load, sometimes not. I would appreciate any suggestions. Again ftp is no problem, publish causes the error.
