I have Advanced running happily under Mac OSX 10.2.8 Server (upgrade will wait for Tiger) and using IWP works fine for Mac clients everywhere. But PC users cannot see the files, even on the IWP homepage. So far FM have no idea why this is. Has anyone experience of this?

Hmm... if this were an OS9 computer and OPEN/HOSTS, I'd recommend verifying that the selected network protocol for FileMaker to use was TCP/IP and not AppleTalk since that could account for that kind of behavior sometimes (Preferences > Application > Network > TCP/IP). OS X Server has a built-in firewall that could be interfering you may want to check, but it won't help explain why Mac web browsers would be able to access IWP and not Windows web browsers. That would be a peculiar discrimination I would have thought could only be detected by filtering browser types.

Post the solution if you find it; try the Server Advanced forum if no one helps here.

Hope you solve the riddle!
