When managing your business finances with QuickBooks, encountering errors can disrupt your workflow and cause frustration. One common issue faced by users is QuickBooks Error H505. This error usually occurs when you try to access a company file that is not located on your computer but on another, and the system setup requires a specific configuration to facilitate this access.

Understanding Error H505

QuickBooks Error H505 is part of a series of errors (H101, H202, H303, and H505) related to hosting settings and network issues. It specifically indicates that the computer on which the QuickBooks company file is located needs additional configuration to enable secure and efficient communication with other PCs on the network. This could be due to improper hosting configuration settings, incorrect DNS settings, or a firewall blocking the communication between the computers.

Symptoms of Error H505

The symptoms are fairly straightforward:

Error message H505 pops up when trying to open a company file on a network.

QuickBooks program window crashes.

PCs might freeze periodically.

QuickBooks can't switch to multi-user mode.

Causes of Error H505

Several factors can lead to this error:

Incorrect hosting configuration settings.

The network data (.ND) file is damaged or incorrect.

QB services like QuickBooksDBXX or QBCFMonitor are not running.

The firewall settings might be blocking the connection to the company file.

Incorrect DNS settings.

Step-by-Step Solutions to Fix Error H505

To resolve QuickBooks Error H505, you can follow these troubleshooting steps. It’s recommended to proceed in order and check if the issue is resolved after each step before moving on to the next.

Step 1: Use QuickBooks File Doctor

Download and run the QuickBooks File Doctor tool. This tool can automatically diagnose and fix common network issues related to QuickBooks.

Step 2: Verify Hosting and Services

Verify Hosting: On each hosting computer, open QuickBooks and go to 'File' > 'Utilities'. If you see 'Host Multi-User Access', this computer is not hosting the file. If 'Stop Hosting Multi-User Access' is visible, select it to disable hosting on this machine. Ensure that only one PC (the server) has the hosting feature enabled.

Verify Services: Make sure that QuickBooks services are running.

Press Windows + R and enter services. msc.

Look for QuickBooksDBXX and QBCFMonitorService.

Ensure both services are set to start automatically and are currently running.

Step 3: Configure Firewall Settings

Configure the firewall settings to allow exceptions for QuickBooks. This can often resolve the issue, as improper firewall settings can block communication between server and client computers.

Step 4: Check the Windows Hosts File

If the error still persists, editing the Windows host file on the computers involved might be necessary.

Locate the hosts file, typically found in C:\Windows\System32\Drivers\etc.

Add the server’s IP address, followed by the computer name.

Step 5: Create a New Network Data File

On the server, browse to the folder containing the QuickBooks company file and locate the corresponding.ND file. Rename the.ND file to . ND.OLD, and reopen QuickBooks; this will create a new one.ND file automatically.

Step 6: Ensure Proper Services Are Running

Go back and double-check that QuickBooks services are running:

QuickBooksDBXX service (XX denotes your version of QuickBooks)

QBCFMonitorService

Ensure these services are set to run as 'Automatic' and start them if they aren't running.

Conclusion 

Resolving QuickBooks Error Code H505 typically involves ensuring proper network settings, configuration adjustments, and sometimes firewall tweaks. By following these steps, you can usually get back to normal operations without significant downtime. If the problem persists after trying these steps, it may be helpful to consult with a professional or reach out to QuickBooks support for further assistance.
