    Alter Firewall Settings to Create Exceptions

    Firewall settings enable or disable certain programs for accessing internet connection. When these ports are blocked, QuickBooks cannot access the internet.

    This becomes a huge problem for anyone who has hosted his or her company file on a separate server. To connect with the company file, QuickBooks must access network connection through specific ports. When a firewall blocks such a connection from completing, you usually get a company file or network error because QuickBooks cannot open the company file nor connect to it.

    In such cases, users must create custom rules for inbound and outbound connections to enable QuickBooks to access the company file through a specific port. While the ports for latest versions of QuickBooks are clearly defined, they aren’t well defined for older versions of the accounting software.

    Steps to Create Firewall Rules for QuickBooks Desktop

    🔷 Press the windows key to open the Start menu.
    🔷 Click on Windows Firewall.
    🔷 From the left panel, select Advanced Settings.
    🔷 Click on Inbound Rules.
    🔷 Click on New Rule from the right panel.
    🔷 Select the radio button against Port.
    🔷 Select Next.
    🔷 Choose TCP, then input the Specific Local Ports that you want to make an exception for.
    🔷 Select next and Click on Allow the connection.
    🔷 Click on Next.
    🔷 Once you’ve selected all the ports, you can choose next to proceed with creating the exception.
    🔷 Input a unique name for this rule. This name makes it easier to identify the rule on a later date if you choose to alter the rule in any manner.
    🔷 Click on Finish.

    Following similar steps create an outbound rule for QuickBooks. Once you’ve created the outbound rule, QuickBooks won’t get interrupted while accessing the network connection. You’ll be able to connect to the separate server that stores the company file. This means that QuickBooks won’t encounter any error when accessing the company file, leading to the resolution of QuickBooks script error.

    Reconfigure your Security Software

    Apart from windows firewall, you may have other security software on your system, which you may have purchased from a third party. These software can sometimes block network connection.

    You need to check if any of the security software in your system is causing the problem. If yes, then you need to proceed with caution and reconfigure the security software so that you can get back to work.


    QuickBooks script error occurs generally because the accounting software cannot connect with the company file. There are many causes, the most serious of them being a permanent damage to the company file. If you can’t resolve Quickbooks script error on your own or believe that the company file is damaged
