Verify QuickBooks Services:

• In the list of services, find “QuickBooksDBXX” (XX represents your version) and “QBCFMonitorService.”
• Ensure both services are set to “Automatic” and are running.
Check Firewall Settings:
• Open the Control Panel and go to “System and Security.”
• Click on “Windows Firewall” and then select “Allow an app or feature through Windows Firewall.”
• Ensure that QuickBooks ports are added and allowed through the firewall.
Ping the Server:
• On the client computer, open the Command Prompt and type “ping [server name]” (replace [server name]
with your server’s name).
• If there is a response, the server is reachable. If not, check network connections.
