In severe cases the conflict could even keep the QuickBooks Database Server (a windows service) from starting-up after a controlled, or unexpected shut-down of the computer hosting QuickBooks. In some prior years, there have been port conflicts between QuickBooks and certain Microsoft Operating System components, most notedly Microsoft DNS, which is a Windows Server-related 'Windows service.' But even when Microsoft OS components were not the source of conflict, other programs and services running on the computer hosting QuickBooks could interfere with the QuickBooks network operations by making use of some, or all, of the firewall ports. For example, in 2018 the following ports had to be open for QuickBooks to work properly in multi-user mode: 8019, 56728, 55378-55382 whether you were using a client-server or peer-to-peer network configuration. The algorithm progressively incremented the port assignments within a wide-range of available ports Microsoft defined for the Windows firewall.

You may not even be aware that ‘firewall port assignments’ for QuickBooks (Desktop) 2019 are different, and I am not simply talking about the port numbers. The entire mechanism is different for 2019 because the newest versions of QuickBooks (Desktop) are using ‘dynamic port assignment’ rather than static port ranges.įor years, QuickBooks has used an algorithm for firewall port assignments needed by QuickBooks Desktop products when running in multi-user mode.
