Top 7 Solutions to Troubleshoot QuickBooks Error H505 When Hosting

If the above steps do not resolve the company file error H505, you will need to perform expert-recommended troubleshooting steps mentioned below in detail.

1. Run QuickBooks Database Server

The server computer is your main computer that hosts your company’s files; others are just connected to your network, known as workstations.

To run this, download and install QuickBooks Tool Hub (1.6.0.8) in the latest release.

• Open the QB Tool Hub.
• Go to Network Issues.
• Click on QuickBooks Database Server Manager. If QuickBooks is not on the server computer, you will be prompted to install it.

• Select Start Scan in the QuickBooks Database Server Manager only if you see your company file folder(s). If you don’t, click Browse and locate the company file location and then select Start Scan.
• The QuickBooks Database Server Manager will automatically repair the firewall permissions. When done, select Close.

Now, open QuickBooks on each workstation where you error code H505. Go to File > Switch to Multi-user Mode. If you are using a server computer as a workstation, make sure to check it too.

2. Run QuickBooks File Doctor

The QuickBooks File Doctor tool verifies the company file data for possible damage and network connectivity issues. If it detects anything, it also runs a quick repair.

• Go to the Company File Issues menu.
• Run QuickBooks File Doctor. the file doctor may take a minute for it to open.

Note: If the QuickBooks File Doctor does not open, type QuickBooks Desktop File Doc in the search and open it manually.

• Now, choose your company file from the drop-down menu in QuickBooks File Doctor. If you don’t, click Browse to find your company file.
• Select Check your Network > Continue.
• Enter the QB admin password to allow the access and click Next.

If you can switch to a multi-user network without any issues, everything if fixed.

3. Make sure the hosting settings are correct

If you see error H505, it means one or more workstations are set to be the server for QuickBooks. The only server is the main computer that hosts your company file, not the connected ones.

Make sure the Host Multi-User option is turned off on all the workstations, as these computers don’t host your company file on the server. The hosting should be turned on only for the server.

Note: Consider doing these steps before opening a company file.

• Open QuickBooks on the workstation where you see H505.
• Do not open the company file. Instead, go to File and select Utilities.
• If you see the option “Host Multi-User Access,” don’t select it. Go to your next workstation, as this one isn’t causing the problem.
• If the option is Stop Hosting Multi-User Access, select it.

• Repeat the same steps on all workstations where you see error code H505.

Once you check on all workstations, move to the server computer, as this is the computer that hosts your company file.

• Open QB Desktop on the server computer.
• Navigate to File and select Utilities.
• Select the Host Multi-User Access only; if this isn’t the option, skip it.

4. Check the services on your server

Important for the Full Program option: If you utilize the full version of QuickBooks on your server PC, first turn on multi-user hosting. Open QB Desktop on the server computer. Go to File > Utilities. Select the Host Multi-User Access option, or if you see Stop Hosting Multi-User Access, don’t select it.

You must ensure that the QuickBooks services are running on the server computer. Follow the steps below for QuickBooksDBXX and repeat the same procedure for QBCFMonitorService.

• Open the Windows Start menu.
• In the search, type Run and press Enter.
• In the Run window, type “services.msc,” then press Enter.

• Look for QuickBooksDBXX on the list and double-click on it. XX is the version of QuickBooks plus 10. Example: QuickBooks 2023 is QuickBooksDB33.
• For the Startup type, choose Automatic.
• Ensure the Service Status is either Running or Started. If it’s neither, select Start.

• Navigate to the Recovery tab.
• Click Restart the Service from the following drop-down menus: First failure, second failure, and subsequent failures.

• Select Apply and click OK to save the changes.
• Repeat the same steps for QBCFMonitorService.

When done, open QB on each workstation. Go to File > Switch to Multi-user Mode. If the company file opens correctly in the multi-user mode, the problem is fixed.

5. Add services to your Windows admin group on your server

Admin permissions are required to access hosting settings or make admin-level changes in QuickBooks, and the same applies to QuickBooksDBXX and QBCFMonitorService, which are required to host the company file successfully. This ensures they have the necessary access to communicate across the network, enabling workstations to connect to the company file. Thus, set up a folder and Windows access permissions to fix QuickBooks error H505.

6. Configure your firewall settings on your server

Windows Firewall is an in-built system security application that controls both inbound and outbound traffic on all ports by default. This ensures your computer’s safety from malware and cyberattacks and protects your data. If the firewall is considered a threat to QuickBooks, it may block all the ports used by QuickBooks processes. To unblock, you will need to configure Windows Firewall for QuickBooks Desktop.

7. Ping your server from a workstation

When you ping a server from a workstation, it runs a test to verify the network connection. Try to ping your server from each workstation, getting error H505.

To start, enable Network Discovery on the server computer and any workstations where you see error code H505:

• Open the Windows Start menu on the server and workstations.
• In the search, type “Network” and open the Network and Sharing Center.
• Choose Change advanced sharing settings.
• Now, turn on network discovery, which should be selected in the Network discovery and File and printer sharing sections.

Now, get the server name from your server:

• Open the Windows Start menu on the server.
• In the search, type Run and open Run.
• In the Run window, type “CMD” and press Enter.
• Type “ipconfig/all” into the CMD window and then press Enter.
• In the Windows IP Configuration section, look for the Host Name. The server name should be on the right.

• Note down the hostname, or simply copy it to a Word document so you have quick access.

Move back to the workstation to test the server. You should get in touch with Windows or IT professionals for these complex steps.

• Open the Windows Start menu.
• Type “Run” in the search and select Run.
• In the Run window, type CMD and press Enter.
• Enter “ping [your server name],” and press Enter. When writing this, avoid using the brackets around the server name.

• Repeat the same steps on each workstation where you encountered error H505.

If you see every packet answered without drops, your server seems healthy. Continue ahead and jump over to solution number five.

If you notice missing packets or delayed replies, pause immediately. Contact a qualified IT expert to receive help with your network.
