You can use the QuickBooks Connection Diagnostic Tool to troubleshoot H202, H505, and 6000 series errors in QuickBooks.

You may also watch a 4 minute video of how to use this tool.
Once you download and install the tool, you can begin to diagnose connectivity on your computer.
The Diagnose Connection tab is the first tab you'll use in the tool and is divided into three sections:
The Product information section displays basic system information.
The version and edition of QuickBooks installed and if the installation type is a server.
If QuickBooks is set up to share (host) company files.
Verification that TCP/IP is set up, and that QuickBooks can identify the hostname of the computer
If TCP/IP display is enabled, the network adapter that is disabled will be displayed
Run IPConfig on the command line (see Windows Help for instructions) and be sure you have an IP address for at least one network adapter. Check that you are able to open a web browser and can go to an Internet or intranet web page.
Note: If you have Windows Vista or later, click the Enable button to enable the specified network adapter.
You can use the QuickBooks Connection Diagnostic Tool when there is no connectivity on any adapters, but client computers won't be able to open company files hosted on this computer. You will be resolving problems on the local machine only.
If you do not have any network connectivity but don't plan on using QuickBooks from other computers, you can ignore this error. If you have more than one adapter in your machine (such as wireless and wired), and one of them is working, you can ignore this error.
Number of IP addresses assigned to the computer
You should see at least one IP address for your system. If more than one IP address appears, this could be a problem. Try disabling all network connections but one to see if this lets you open the company file. You might have to restart the computer for this change to take effect.
Disable network adapters
Number of network interfaces set up on the computer
The Firewall Status section displays information about your firewall. The tool may be able to automatically configure your firewall, or you can also configure your firewall manually.
Whether the internal Windows Firewall is enabled
Lets the tool configure the Windows Firewall ports for QuickBooks.
Note: If the button is inactive (grayed out), the ports are already configured correctly.
Whether the tool detects a firewall.
Note: The QuickBooks Connection Diagnostic Tool does not detect all third-party firewalls.
If a third-party firewall is detected, use the firewall manufacturer's steps to open all the required ports so that QuickBooks can function properly. Also go through the firewall configurations to ensure that no QuickBooks applications are in the Blocked lists. You can also configure your firewall manually.
The Test Connectivity section lets you test your computer's connectivity.
This test checks whether the folder has the necessary permissions to access the file. If Port Finder Status and DB Service status are green, but Company File Directory Accessible status is red, click the Scan Folders tab and scan the folder to fix the permissions and ND file path.
Important: You can only use the Scan Folders feature on the server.
You should also check to make sure your company file folder is setup to open a company file from another computer.
Important: The Scan Folders tab is available only when the QuickBooks Connection Diagnostic Tool is installed on a computer that has the QuickBooks Database Server Manager installed.
The Scan Folders tab can find damage in the QuickBooks Network Data files (.nd files) where critical company file hosting information is stored. It can also corrects or sets permissions required for QuickBooks to operate in a multi-user environment. You can also use the Share Folders button to share the folder in Windows with the necessary users.
To scan all folders on the server that is hosting the QuickBooks company file, and ensure that client computers can open the files:
You will see 3 columns for each file or folder scanned: ND File Status, Permission Status and Folder Shared.
Note: The ND file is the QuickBooks Network Data file.
The View Log tab displays the contents of the log file, which records unforeseen conditions, errors, and QuickBooks messages. The log file does not record Windows errors, or errors from other applications. Use this with the assistance of a support agent.
