How to Resolve QuickBooks Error Code H505

Resolving QuickBooks Error Code H505 involves a series of troubleshooting steps. Below is a detailed guide to help you fix the error:

Step 1: Verify Hosting Configuration

Ensure that only the server computer is set to host multi-user access and that all other workstations are not:

1. Open QuickBooks on each workstation.
2. Go to the “File” menu and select “Utilities.”
3. If you see the option “Host Multi-User Access,” this computer is not hosting the company file. Do not change anything.
4. If you see the option “Stop Hosting Multi-User Access,” click on it to disable hosting.
5. Repeat these steps on each workstation to ensure that only the server computer is hosting.

Step 2: Use QuickBooks File Doctor

The QuickBooks File Doctor is a built-in tool designed to diagnose and fix common QuickBooks file and network issues. Here’s how to use it:

1. Download and Install QuickBooks Tool Hub:

   • Download the QuickBooks Tool Hub from the official Intuit website.
   • Install the Tool Hub by following the on-screen instructions.

2. Run QuickBooks File Doctor:

   • Open QuickBooks Tool Hub.
   • Click on the “Company File Issues” tab.
   • Select “Run QuickBooks File Doctor.”
   • In the File Doctor window, select your company file and choose “Check your file” and then “Continue.”
   • Enter your QuickBooks Admin password and click “Next.”

The QuickBooks File Doctor will scan your company file and attempt to repair any issues it detects.

Step 3: Configure Firewall and Security Settings

Your firewall or security software may be blocking QuickBooks from accessing the company file. Configure your firewall to allow QuickBooks access:

1. Add QuickBooks to the Firewall Exception List:

   • Open your firewall settings.
   • Navigate to the “Exceptions” or “Allowed Programs” section.
   • Add QuickBooks and its components (e.g., QBW32.exe, QBDBMgrN.exe) to the list of allowed programs.

2. Open Required Ports:

   • Ensure that the ports required by QuickBooks are open. The specific ports depend on the version of QuickBooks you are using. You can find the specific ports for your version on the Intuit website.
   • Open these ports in your firewall settings.

Step 4: Rename the .ND and .TLG Files

The .ND and .TLG files are configuration files that allow QuickBooks to access a company file in a network or multi-user environment. Renaming these files can resolve the error:

1. Open the folder containing your company file.
2. Find the files with the same name as your company file but with extensions .ND and .TLG (e.g., CompanyFileName.qbw.nd and CompanyFileName.qbw.tlg).
3. Right-click each file and select “Rename.”
4. Add “.old” to the end of each file name (e.g., CompanyFileName.qbw.nd.old and CompanyFileName.qbw.tlg.old).
5. Open QuickBooks and try accessing your company file again. QuickBooks will recreate these files when you open the file.

Step 5: Use the QuickBooks Database Server Manager

The QuickBooks Database Server Manager ensures that the database is properly configured for multi-user access. Here’s how to use it:

1. Install QuickBooks Database Server Manager:

   • If it’s not already installed, download and install the QuickBooks Database Server Manager from the Intuit website.

2. Scan Your Company File:

   • Open QuickBooks Database Server Manager.
   • Click on the “Scan Folders” tab.
   • Click “Add Folder” and browse to the location of your company file.
   • Click “Scan.”

The QuickBooks Database Server Manager will scan your company file and ensure it is properly configured for multi-user access.

Step 6: Verify the QuickBooks Services

Ensure that the QuickBooks services are running on your server:

1. Open the Run Command:

   • Press Windows + R keys to open the Run command.
   • Type “services.msc” and press Enter.

2. Locate QuickBooks Services:

   • In the Services window, locate “QuickBooksDBXX” (where XX is the version of QuickBooks) and “QBCFMonitorService.”

3. Check Service Status:

   • Ensure that both services are running. If not, right-click on each service and select “Start.”
   • Set the Startup Type to “Automatic” for both services.

Step 7: Edit the Host File

Editing the host file can help ensure that QuickBooks can communicate with the server hosting the company file:

1. Open Notepad as Administrator:

   • Press Windows + S and type “Notepad.”
   • Right-click on Notepad and select “Run as Administrator.”

2. Open the Host File:

   • In Notepad, click on “File” and select “Open.”
   • Navigate to C:\Windows\System32\Drivers\Etc.
   • Select “All Files” from the drop-down menu to view the host file.
   • Open the “hosts” file.

3. Edit the Host File:

   • Add the IP address and computer name of the server hosting the company file at the end of the host file.
   • Save the changes and close Notepad.
