What is QuickBooks H505 Error?

QuickBooks H505 Error is a multi-user mode error that occurs when a user tries to access a company file located on another computer, but QuickBooks fails to connect to the server. This error indicates that the hosting configuration settings are incorrect or that there is a problem with the network.

Common Error Message

The error message usually reads: “Error H505: The company file is on another computer, and QuickBooks needs some help connecting.”

Causes of QuickBooks H505 Error

Understanding the root causes of QuickBooks H505 Error is essential for effective troubleshooting. Common reasons include:

Incorrect Hosting Configuration

If the hosting settings are not configured correctly on one or more computers in the network, QuickBooks may fail to connect to the company file, triggering Error H505.

Missing or Damaged .ND File

The .ND (Network Data) file allows QuickBooks to access the company file in a network. If this file is missing or damaged, QuickBooks may encounter Error H505.

Firewall Blocking Communication

Firewalls or security software on your computer or network can block communication between QuickBooks and the server, leading to Error H505.

DNS Issues

Incorrect DNS settings or server IP address problems can prevent QuickBooks from locating and connecting to the server hosting the company file.

QuickBooks Services Not Running

QuickBooks services such as QuickBooksDBXX and QBCFMonitorService must be running for multi-user mode to function correctly. If these services are stopped, you may encounter Error H505.

How to Fix QuickBooks H505 Error

Resolving QuickBooks H505 Error involves a series of steps to identify and rectify the underlying issues. Follow these methods to fix the error and restore multi-user functionality.

3. Right-click on "Inbound Rules" and select "New Rule."
