I needed to fix a small client network this week that had lost access to QuickBook’s on their server. A quick Google and this TechRepublic article gave me the port information I needed to get them back up and running again. I also discovered that Intuit have a “Network Diagnostic Tool” available to help diagnose QB networking issues. I tried it this week and it seems to work well enough – run it with admin rights and it can open the ports in the Windows Firewall for you.

Anyway, for future reference the firewall ports for QB 2009 to 2012 are:
