To restore proper Multi-User functionality, follow these steps:
1. Verify Hosting Settings​
Ensure that only the server computer has hosting enabled.
Open QuickBooks on each workstation.

Open the Tool Hub and go to the Network Issues tab.
Select QuickBooks Database Server Manager.
Click Start Scan and choose the folder where your company file is stored.
Restart the service and try accessing the company file again.
3. Check Windows Firewall and Security Settings​

QuickBooks 2024: 8019, 56728–52430
Add exceptions for QuickBooks programs like QBW32.exe and QBDBMgrN.exe.
4. Rename the .ND and .TLG Files​
