Stored on a network server . . . is the db hosted by FileMaker Server?
Compare what you have set up currently to the recommended configuration for hosting a FileMaker Database.
On the Server computer, the file should be opened by FileMaker Pro with sharing enabled or with FileMaker server. The application that opens the file for hosting should be installed on the server hardware.
All clients then launch their copy of FileMaker Pro and use Open Remote to find and open the database file.
It sounds like you have a file in a shared directory on the server and the first client to open the machine with FileMaker Pro then becomes the host of the file. Not only is this not the recommended way to host a FileMaker Database, it can result in a damaged database file.
Thank you both for your responses.
Phil, you have it exactly right - the database file is in a shared directory on the server, and the expectation my clients had was that whoever was first to the file should be able to open it and become the host. They are not running FileMaker Server on the server, they are simply using a shared folder to store the files where they can be accessed by everyone.
I will reach out to my clients and let them know that the way they've always used this database is not recommended, and see if we can get FileMaker Pro installed on the server and running as the host.
I'll let you know how it all works out.
I suggest that you have them run a recover on this file to check it for damage.
And what I posted does not explain why one client could access the file and another couldn't.
With older versions of FileMaker, sometimes there is an issue with the .PEM files on that computer. If this might be the case..
