Thank you for your post.
Do you have another copy of FileMaker Pro running on that machine? Do you have FileMaker Server running on the machine? This information is covered in Knowledge Base Article #6899 at:
Within FileMaker Pro, are you able to Open Remote hosted files?
Thanks for the quick Reply TSGAL.
I have no other version of FileMaker Pro running or installed on the system. Again, I also did a pot scan and found nothing using port 5003. I read that article too before asking the question. Is there anything else I can check?
For some reason, FileMaker Pro is seeing a conflict with port 5003.
Create a new user account, login to the new user account, launch FileMaker Pro, create a new file and try to turn on Network Sharing.
If the issue still occurs, then uninstall FileMaker Pro, remove the Applications -> FileMaker folder, and reinstall FileMaker Pro, as this will write all new files. On the other hand, if the issue doesn't occur, then FileMaker Pro is not the issue, but there is something in the original user account that is causing the conflict. Try removing the FileMaker Preferences files at:
[User Account] -> Library -> Preferences -> com.filemaker.*
Relaunch FileMaker Pro and try again.
Just a follow-up. I've tried everything suggested but had no luck. So I decided to reimage the system and start with FileMaker. That worked. I have now added most of my applications, and the service is still working as advertised. So obviously, there was something that was either holding the port or causing some type of corruption to FileMaker.
I will repost if I find any additional information that is beneficial to this situation
Thanks for your support TSGal.
Hi Tom! Sounds like you have resolved this issue since last year. But I have the exact same issue with FMPro 9 not sharing since upgrading to macOS Sierra 10.12.x . I found a helpful workaround in help.filemaker.com, specifically Error Message: "FileMaker cannot share files because another user is already sharing files using FileMaker Pro on this … (you may have to log in as a user to read) .
The ONLY thing that worked for me, per one of the suggestions, was to "log in with a [Full Access] account name and password and temporarily disable all Extended Privileges for that account." Which means open your unsharable DB, go to Manage --> Accounts & Privileges --> Extended Privileges, and edit the [fmapp] Extended Privileges by turning off the items listed under "Access via FileMaker Network". You will then be notified that users without passwords could have access to your files. For us, this wasn't an issue, but for you, maybe it is. But this solved the problem: in opening the file again, FMPRo didn't even ask whether the user wanted to share it or not, it just did.
I'm awaiting more possible help from the above forum and hope to pay it forward here. Good luck! —M
