    After running QuickBooks File Doctor, check if you can open the QB company file. If you still cannot communicate with the company file due to the firewall, move to step 3 and manually configure the firewall settings.

    Step 3 – Manually Configure the Firewall Settings

    If you can’t remove firewall blockages with QB File Doctor, manually configure the firewall settings. To configure the firewall, create Windows firewall exception rules for QuickBooks in the following manner –

    Create Firewall Exception Rules for QB Ports

    Adding QuickBooks port exceptions in the Windows firewall will allow QuickBooks to connect to the internet, and it will be able to communicate with the company file without interruptions. Follow the steps given below to create firewall exceptions for QB ports –

    Note: If you have more than one QB version on the same computer, you must configure the firewall settings for each version. Moreover, you need to include each version’s port number in the “specific ports” field in step 4 below.

    1. Type “Windows Firewall” in the Windows search panel, open the firewall, and then go to Advanced Settings.
    2. Further, right-click Inbound Rules, click the New Rule option, and select Port.
    3. Hit Next, ensure TCP is checkmarked, then refer to the following list to find the specific port numbers as per your QuickBooks version.
      • QuickBooks Desktop 2020 and later: 8019, XXXXX.
      • QuickBooks Desktop 2019: 8019, XXXXX.
      • QuickBooks Desktop 2018: 8019, 56728, 55378-55382.
      • QuickBooks Desktop 2017: 8019, 56727, 55373-55377.
    4. Now, enter the port number in the Specific Local Ports field, then click Next.
    5. If you use QBDT 2019 or future versions, add the Dynamic Port Number as per your QB version. To find the Dynamic Port Number, go through the following steps –
      • Type “QuickBooks Database Server Manager” in the Windows search panel, open the program, and select Port Monitor.
      • Further, locate your QBDT version, note the port number, and include it in the port exceptions list.

        Note: You can click Renew to change the assigned port number (for QBDT 2019 and future versions). To renew the port number, go to the Scan Folder menu, click Scan Now, and reset the Windows firewall permissions.
    6. Click Next,select Allow the Connection, then click Next again, and ensure all profiles are marked (if required).
    7. Select Next,create a new exception rule named “QBPorts(year),” and hit Finish to save the rule.
    8. Lastly, repeat these steps to make Outbound Rules for QuickBooks ports. Perform Steps 1 to 7 above, but choose Outbound Rules instead of Inbound Rules in Step 2 to create these rules.

    After creating QB port exceptions, rerun QuickBooks in multi-user mode and check if QuickBooks can communicate with the company file. If the firewall is blocking incoming and outgoing communication, create firewall exception rules for QB executable files.

    Create Firewall Exception Rules for QB Executable Files

    There are several executable files that QuickBooks uses to perform various tasks. You must create firewall exception rules for these files in the following manner –

    • Enter “Windows Firewallin the Windows search panel, then launch the program and move to Advanced Settings.
    • Next, right-click Inbound Rules, select New Rule, and click the Program option.
    • Hit Next, click This Program Path, then select Browse and pick an executable (.exe) file from the below-referred list –
    Executable filesLocation
    AutoBackupExe.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    Dbmlsync.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    DBManagerExe.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    FileManagement.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    FileMovementExe.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    QuickBooksMessaging.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    QBW32.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    QBDBMgrN.exeC:\Program Files\Intuit\QUICKBOOKS YEAR
    QBServerUtilityMgr.exeC:\Program Files\Common Files\Intuit\QuickBooks
    QBCFMonitorService.exeC:\Program Files\Common Files\Intuit\QuickBooks
    QBLaunch.exeC:\Program Files\Common Files\Intuit\QuickBooks
    QBUpdate.exeC:\Program Files\Common Files\Intuit\QuickBooks\QBUpdate
    IntuitSyncManager.exeC:\Program Files\Common Files\Intuit\Sync
    OnlineBackup.exeC:\Program Files\QuickBooks Online Backup
    • Further, select Next, click Allow the Connection,and hit Next again.
    • Now, ensure all the profiles are selected (if required), then hit Next, create a rule named “QBFirewallException(name.exe),and hit Finish.
    • Lastly, follow this same process to create outbound rules for the executable files.While making the outbound rules, follow Steps 1 to 6 above, but select Outbound Rules rather than Inbound Rules in Step2.

    Now, rerun QuickBooks in multi-user mode and check if QuickBooks can communicate with the company file. However, if QuickBooks cannot communicate due to a network problem even after configuring the firewall, move to step 4 and configure the antivirus.

    Step 4 – Configure Antivirus Settings

    Misconfigured antivirus settings can cause restrictions that prevent users from connecting to the company file. Thus, you need to configure the antivirus settings to ensure QuickBooks has proper permissions to connect to the internet. To modify the settings, go through your antivirus program’s specific steps and instructions. To learn how to configure the antivirus settings, either visit the antivirus’s official website or contact your vendor for instructions.

    Now, rerun QuickBooks and try to access your company file to ensure that the communication issues are fixed.

    Solution 2 – Update QuickBooks to the Latest Release

      Note: You can leave the default selections in the Configure Share settings window and click Next again.

    Once the file access and sharing permissions are set, rerun QuickBooks and check if you can access the company file. If you can’t open your company file in QuickBooks Desktop, move to the next troubleshooting solution.

    Solution 4 – Run the QB Database Server Manager

    QuickBooks Database Server Manager is an essential utility that is used to run scans and fix network issues in QB. It lets users share their QuickBooks company files with other PCs over the network. Before running the tool, ensure QB Tool Hub is installed (see ‘Step 1: Install the Latest QB Tool Hub’ of ‘Solution 1: Configure Windows Firewall Settings’ above).

    3. The QuickBooks Database Server Manager will automatically repair your firewall permissions and fix the network issues. When the scan process is complete, select Close.
    4. Next, find and open the folder you scanned and ensure there’s a Network Data file in it (for example, [your company file]qbw.nd). If you don’t see the .ND file, follow the same steps and scan the folder again.

    Now, rerun QBDT and check if the company file issues are resolved. However, if QuickBooks Database Server Manager can’t connect to your company file, follow the next solution and fix the problem.

    1. Open QuickBooks on one of your workstations, go to the File menu, and select the Utilities tab.
    2. If you see the Stop Hosting Multi-User Access option, select it to disable the multi-hosting. However, no action is required if you see the Host Multi-User Access option, and you can move on to the next workstation.

    After you check all of your workstations, move on to your server PC and reset the QB hosting settings by using the steps below –

    3. Repeat this process and select Stop Hosting Multi-User Access to reset the QB multi-user mode.
    4. Repeat the process again, and select Host Multi-User Access to finish the process.

    Try accessing your company file once the multi-user mode is correctly set on the server and workstations. If you still encounter the “QuickBooks cannot communicate with the company file” error, move to solution 6.

    Solution 6 – Disable Password-Protected Sharing in Windows

    If none of the above solutions work, modify the network settings in Windows. Sometimes, sharing settings on your system might prevent QuickBooks from connecting to the company file. To fix this, turn off password-protected sharing in the following manner –
