PS- I am working off of Filemaker Pro 11. Thanks!
How are you hosting the file?
How are they connecting to it?
Do they get a password dialog from FileMaker when they should not, or...? (Please describe exactly what is happening when they get a "permission denied" response.)
Safest way to share the file without using FileMaker Server is:
1) Open the file with FileMaker Pro installed and running on the same machine where the file is stored
2) Other users then launch FileMaker and use Open Remote... to find and open the hosted file.
Failure to host the file in this manner (or with FileMaker Server), risks damage to your file.
Thanks for your response.
I realized that the team was trying to open the master file off of our database instead of using the "open remote function" I helped them figure out the open remote function and it looks like we're all good to go now.
