I did use Favourite Hosts, and the server and accompanying files appear okay. It's just that when I try to open a file from the list, the coffee cup cursor just sits there for a minute and then FileMaker gives up and nothing happens.
I have successfully opened FileMaker files via VPN for another client, but that client is running FM Server 9 on Windows XP, and I am opening the file on Windows XP.
That's why I'm wondering if it's a problem connected with me opening the files from XP and the files being served on Mac OS, and whether anyone else has had the same problem, but more importantly a solution.
