I wish I could be more help. Judging from a post in another thread, all the FM tech people are busy helping out in the Bento forum for at least one more day.
Your post sounded familiar. Perhaps this thread will help: Filemaker Advanced Pro 8.5v2 cannot see "Open Files" post upgrade
You can also used the Advanced link above to search other threads that might help.
What confuses me is that the server was up and running and installed before September 2008. And that my previous installation of my laptop worked fine.
We seem to only see this with recent installs of filemaker 8.5 on Mac.
There is another Mac, running Tiger, that has multiple versions of filemaker running (7.5, 8, 8.5). The databases can be seen and opened with 7.5 and 8 on that machine but not 8.5.
Thank you for your posts.
The information from Knowledge Base article #6955 is correct.
Uninstall FileMaker Pro 8.5, set your system clock prior to September 22, 2008, and reinstall FileMaker Pro 8.5.
You should then be able to see the files remotely.
