  1. QuickBooks Error H303 | Top Methods to Troubleshoot

  2. Users of the QuickBooks software can operate in single-user or multi-user modes. They could frequently need to move between one mode and the other. But when they do, they might get the QuickBooks error H303, which says that QuickBooks requires some assistance connecting because the company file is on another computer. It indicates that there is an issue with QuickBooks’ network connection. Such a mistake needs to be corrected right away because it might negatively impact businesses’ productivity and cause delays in getting work done. When QuickBooks is operating in multi-user mode, there should be one server computer hosting the company files and numerous workstation computers connecting to the network to access the files. Incorrect hosting settings, such as turning hosting on or off in any workstation or on the server computer, maybe the cause of this problem. The hosting settings of the server computer and the workstations can be examined by users, and the necessary adjustments can be made to resolve this mistake. They might also use the QuickBooks Tool Hub’s Database Server Manager. Continue reading this article until the end to discover more about the causes of this problem and the solutions available. Do you require assistance with the QB Error H303 or any other QuickBooks Multi-User mode-related problems? Call 1-855-856-0042 to speak with a member of our technical support staff.

  3. What are a few likely causes of the QuickBooks Error Code H303? • One of the H series problems in QuickBooks is the H303 error, which denotes a break in the communication between the server and QuickBooks Multi-User mode. The following are some potential causes that could do so:- • Your system’s QuickBooks network data files may be destroyed or faulty. • The connection between the server computer and the workstations may be blocked by your PC’s Windows firewall. • You may need to configure your server computer’s hosting settings in order to host multi-user mode. • You may need to adjust the hosting settings on one or more of your workstations because they may be configured to host multiple users. • The server PC is where QuickBooks services like the QuickbooksDBXX and QBCFMonitor are designed to run. They may have been prevented from running by something. • It’s possible that QuickBooks doesn’t have the admin rights necessary to host multi-user mode.

  4. What techniques are available to fix the H303 Error in QuickBooks? You can use the following troubleshooting techniques to resolve the H303 problem in QuickBooks:- Utilize the QuickBooks Database Server Manager and the QuickBooks File Doctor Tools located in the Tool Hub on your server PC. • Use the tools listed above, which may be found in the QuickBooks tool hub, along with the following procedures to promptly fix the issue:- • On the server computer, first, download the QuickBooks tool hub from Intuit’s official website. • Install QuickBooksToolHub.exe by saving it to an accessible location and installing it now. • To launch it, select the QuickBooks Database Server Manager option from the tool hub. • Now scan your company’s files by choosing Start Scan. • Reopen the tool hub and go to the corporate file issues section after the scan is finished. • To restore any damage to the QuickBooks Company files, launch the QuickBooks File Doctor application now. • Once the utility is finished, restart your computer and enter multi-user mode once more.

  5. Examine the hosting options on your server PC and make any necessary configurations. • To be able to host multi-user mode, your server computer’s hosting settings must be enabled. These steps can be used to review and configure them:- • After starting the QuickBooks program on your server PC, go to the File menu. • Now navigate to this menu’s Utilities section. • If it is not already chosen, click Host Multi-User Access to activate the hosting settings. • You should be able to enter multi-user mode now that your server machine is configured to host files. Review the hosting settings on each of your workstations and make any necessary configurations. • Since there should only be one server machine hosting the files, all workstations in QuickBooks multi-user mode must have their hosting settings disabled. These methods can be used to check and modify these settings:- • Open the QuickBooks software on each of your workstations, then go to the File menu. • Now navigate to this menu’s Utilities section. • If the host multi-user access option is selected, disable the hosting settings by selecting the stop hosting multi-user access option. • You should be able to enter multi-user mode now that your workstation’s hosting configurations are in order.

  6. Verify that the QuickBooks services QBCFMonitor and QuickbooksDBXX are active on your server PC. • Follow the procedures listed below to see if QuickbooksDBXX (or XX, depending on your QuickBooks version) is running on your server machine. Next, follow these steps to see if QBCFMonitor services are available:- • On your server computer, type services.msc in the Run dialogue box and press the Enter key. • Double-click QuickbooksDBXX from the list that displays, then pick Automatic as the Startup Type. • If the service is not already operating or launched, you must start it. • Select Restart the Service from the First failure, Second failure, and Subsequent failures drop boxes by hovering your cursor over the Recovery tab. • Once you’ve saved the modifications, try to switch QuickBooks to multi-user mode.

  7. Manually add a firewall port exception for QuickBooks on your computer. • To prevent your windows firewall from blocking the connection between server computers and workstations, you must add a firewall port exception for QuickBooks with the below-mentioned steps:- • Access your windows firewall from the start menu and head to its Advanced Settings. • Right-click on the Inbound Rule option, then select New Rule. • Select the Next option after clicking on the Port option. • After ensuring that TCP is selected, enter the specific ports for your QuickBooks year version in their specific local ports field. • Moving forward, Allow the connection and make sure to mark all profiles if asked. • Finally, finish by creating a rule named QBPorts(year). • Now repeat the same steps for Outbound rules by right-clicking on Outbound Rules instead of Inbound Rules in the advanced settings. • If the error continues, create a windows firewall exception for QuickBooks Programs by right-clicking Inbound Rules and selecting Program. • Then go to This Program Path and select Browse. • Look for executable files (.exe) and Allow the Connection. • Make sure to mark all profiles if asked, and then create a rule named QBFirewallException(name.exe). • Now repeat the same steps for Outbound rules by right-clicking on Outbound Rules instead of Inbound Rules in the advanced settings.

  8. You can use these techniques to get rid of QuickBooks Error H303. Since such errors can adversely affect your company’s work efficiency, you must address them at the earliest and continue using QuickBooks smoothly in both modes. By paying attention to your server computer’s and workstation’s hosting settings, you can prevent issues in QuickBooks’ multi-user mode. You must also ensure that QuickBooks has the admin privileges allowed for multi-user mode connection. Always check to ensure that no third-party software prevents QuickBooks from connecting to the server. We advise you to apply the strategies in this article in the order they are listed.
