Are your employees unable to access the QuickBooks company file? Is the multi-user setup broken? The culprit may be your Windows Firewall. By default, the firewall may block QuickBooks’ essential services, such as the Database Server Manager or QuickBooks background processes.
You’ll need to manually add port exceptions (like 55378–55382) and give full access to QuickBooks-related .exe files. QuickBooks Tool Hub can automatically handle this if you're unsure about doing it manually.
Don’t let a blocked firewall bring your business to a halt. With Smith’s expert help at QuickBook SupportNet, you can resolve firewall issues quickly and restore smooth business operations.
