What is QuickBooks Error Code H505?
QuickBooks Error Code H505 belongs to the H-series of errors, which primarily occur in multi-user mode. This error indicates that the workstation is unable to establish a connection with the company file that is stored on a server. In simpler terms, Error H505 means that QuickBooks is unable to communicate with the host system where the file is stored.
What Triggers QuickBooks Error H505?
Several factors can contribute to QuickBooks Error H505:
1. Improper Hosting Configuration
The most common cause of Error H505 is incorrect hosting configuration. When the hosting settings are not properly set, QuickBooks cannot access the company file.
2. Blocked Communication
Firewall settings can prevent QuickBooks from communicating with the server where the company file is stored. If the firewall blocks access, the error may occur.
3. DNS Issues
Issues with the DNS (Domain Name System) can also trigger the error by interfering with the connection between the host and workstations.
4. Damaged or Missing Network Data File (.ND File)
The .ND file is a configuration file that allows QuickBooks to access company files in a network or multi-user environment. If this file is damaged or missing, QuickBooks won’t be able to locate the company file, leading to Error H505.
5. QuickBooks Services Not Running
Certain QuickBooks services like QuickBooksDBXX (where XX represents the version of QuickBooks) and QBCFMonitorService need to be running on the server for QuickBooks to work in multi-user mode. If these services are not active, it can cause Error H505.
How to Fix QuickBooks Error Code H505
Now that we know the causes of the error, let's dive into the steps to resolve it.
1. Check and Correct Hosting Settings
Incorrect hosting settings are often the root cause of Error H505. Ensure that only the server (the computer where the company file is stored) is set to host multi-user access. No other workstation should have hosting enabled.
Steps to Correct Hosting Settings:
- Open QuickBooks on each workstation where you encounter the error.
- Go to File Utilities.
- If you see the option Host Multi-User Access, it means that workstation is not hosting, which is correct. Do not change it.
- If you see Stop Hosting Multi-User Access, select it to turn off hosting on that workstation.
- Make sure only the server has hosting enabled.
2. Configure the Firewall to Allow QuickBooks Communication
Firewalls can block QuickBooks from accessing the network. Configuring your firewall to allow QuickBooks through can resolve Error H505.
Steps to Configure Firewall:
- Open the Control Panel on the server and go to System and Security.
- Click on Windows Defender Firewall and select Advanced Settings.
- In the Inbound Rules section, create a new rule for QuickBooks by clicking New Rule.
- Choose Program and navigate to the QuickBooks program file path.
- Allow the connection and apply the rule for TCP ports 8019, 56728, 55378-55382.
- Repeat the same steps for Outbound Rules.
- Restart your system and try opening the company file again.
3. Create a New .ND File
A damaged or missing .ND file can cause QuickBooks to fail in multi-user mode. Creating a new .ND file can resolve the error.
Steps to Create a New .ND File:
- Go to the folder where your company file is stored.
- Look for the .ND file associated with your company file (e.g.,
MyCompanyFile.QBW.ND). - Right-click the .ND file and select Rename.
- Add
.oldat the end of the file name (e.g.,MyCompanyFile.QBW.ND.old). - Open QuickBooks and navigate to File Utilities Host Multi-User Access.
- QuickBooks will automatically create a new .ND file.

- Type services.msc and hit Enter.
- Scroll through the list and locate QuickBooksDBXX (where XX corresponds to your version of QuickBooks).

6. Check the DNS Settings
Incorrect DNS settings can also contribute to Error H505. You can resolve this by configuring the DNS server on the server and workstations.
Steps to Configure DNS:
- Open the Run dialog box on both the server and the workstation.
- Type cmd and hit Enter.
- In the Command Prompt window, type ipconfig /flushdns and hit Enter.
