Thanks for providing in-depth details of your concern, treichhart.
QuickBooks Desktop uses a database file manager to communicate with the company file. The recommended multi-user set up is having the company file stored on the Host computer. We can turn on hosting only for the Host computer or where the company file is stored. If you're using a server to host your file, one computer still has to act as a Host. We must not turn on hosting for workstations. Here's how to turn it on:
- Go to the File menu, and then select Utilities.
- Select Multi-User Access.
- Click Yes to confirm.
Once turned on, please follow these steps:
- Go to your server computer (a computer where you store your company file).
- Click the Start menu, and then type Database.
- Select QuickBooks Database Server Manager.
- If you can't see your folder location, click Browse, and then choose your company file.
- Click OK.
- Select Start Scan. This will repair your firewall permission to allow QuickBooks to communicate with your network.
- Click Close, and then try opening QuickBooks in Multi-user mode on your workstations.
