Troubleshooting QuickBooks Error H505

Now that we understand the symptoms and causes, let's explore the troubleshooting steps to resolve QuickBooks Error H505.

Step 1: Verify Hosting Settings

Ensuring that only the server computer hosts the QuickBooks company file is crucial for resolving Error H505.

1. Check Hosting Settings on Workstations:

   • Open QuickBooks on each workstation.
   • Go to the File menu and select Utilities.
   • Ensure that Host Multi-User Access is not selected. If it is, select Stop Hosting Multi-User Access.

2. Check Hosting Settings on the Server:

   • Open QuickBooks on the server computer.
   • Go to the File menu and select Utilities.
   • Ensure that Host Multi-User Access is selected.

Step 2: Configure Firewall Settings

Improper firewall settings can block QuickBooks from accessing the server. Configuring the firewall to allow QuickBooks through can resolve the issue.

1. Add Firewall Exceptions:

   • Open your firewall settings.
   • Locate the option to add exceptions or allow programs through the firewall.
   • Add QuickBooks executable files (QBW32.exe, QBUpdate.exe, and QBDBMgrN.exe) to the exception list.
   • Ensure that ports 8019, 56728, and 55378-55382 are open.

2. Restart the Computer:

   • After adding exceptions, restart your computer to apply the changes.

Step 3: Check DNS Settings

Incorrect DNS settings can prevent QuickBooks from locating the server hosting the company file.

1. Flush DNS:

   • Press Windows + R to open the Run dialog box.
   • Type cmd and press Enter to open the Command Prompt.
   • Type ipconfig /flushdns and press Enter.

2. Edit the Windows Hosts File:

   • Navigate to C:\Windows\System32\Drivers\etc.
   • Open the hosts file using Notepad.
   • Add the server IP address and server name at the end of the file (e.g., 192.168.1.100 ServerName).
   • Save the file and close Notepad.

Step 4: Ensure QuickBooks Services are Running

QuickBooks services like QBDBMgrN need to be running on the server to facilitate multi-user access.

1. Check QuickBooks Services:

   • Press Windows + R to open the Run dialog box.
   • Type services.msc and press Enter to open the Services window.
   • Locate QuickBooksDBXX (where XX is the version of QuickBooks) and QBCFMonitorService.

2. Set Services to Automatic:

   • Right-click on each service (QuickBooksDBXX and QBCFMonitorService) and select Properties.
   • Set the Startup type to Automatic.

Step 5: Repair or Replace the Network Data File (.ND)

The .ND file allows QuickBooks to access the company file over the network. Repairing or replacing this file can resolve network issues.

1. Locate the .ND File:

   • Open the folder containing your QuickBooks company file.
   • Locate the file with the same name as your company file but with a .ND extension (e.g., CompanyFileName.qbw.ND).

2. Rename the .ND File:

   • Right-click on the .ND file and select Rename.
   • Add .OLD at the end of the file name (e.g., CompanyFileName.qbw.ND.OLD).

3. Rescan the Company File:

   • Open QuickBooks Database Server Manager (found in QuickBooks Tool Hub under the Network Issues tab).
   • Click on Start Scan and browse to the folder containing your company file.
   • Click OK to start the scan.

Step 6: Use QuickBooks File Doctor

QuickBooks File Doctor is a tool designed to diagnose and repair issues with your company file and network setup.

   • Follow the on-screen instructions to complete the repair process.

Step 7: Restart All Computers

Restarting all the computers connected to the network can help refresh network settings and resolve the error.

1. Restart Workstations:
   • Restart all workstations connected to the network.
2. Restart the Server:
   • Restart the server computer hosting the QuickBooks company file.
