Solution 1: Check Hosting Settings
Ensure that the hosting settings are correct on all computers:

Solution 2: Use QuickBooks Database Server Manager
The QuickBooks Database Server Manager helps manage network setup:

- Open Tool Hub: Once installed, open the QuickBooks Tool Hub.
- Run Database Server Manager: Click on ‘Network Issues’ and then ‘QuickBooks Database Server Manager.’

Solution 3: Configure Firewall Settings
Ensure that the firewall is not blocking QuickBooks:
