What Is QuickBooks Error H202?
QuickBooks Error H202 occurs when QuickBooks Desktop is set up in multi-user mode but cannot connect to the company file located on a different system (the server). This communication gap between the user system and the server usually results from misconfigured network settings or blocked connections.
When this error pops up, it typically displays the following message:
"You are trying to work with a company file located on another computer, and this copy of QuickBooks cannot reach the server (H202)."
This issue may seem like a small hiccup, but it can lead to serious disruptions in your accounting tasks and potential data loss if not resolved quickly.
Causes Behind QuickBooks Error H202
Understanding the root causes is key to resolving QuickBooks Error H202 effectively. Here are the most common culprits:
Incorrect Hosting Configuration – QuickBooks services might not be correctly set up to allow multi-user access.
Blocked QuickBooks Ports – The ports required by QuickBooks to communicate over the network may be blocked by a firewall.
Damaged .ND File – The Network Data (.ND) file may be corrupted or misconfigured.
QuickBooks Database Server Not Running – This essential service may not be running on the host machine.
DNS Server Issues – Incorrect DNS settings can prevent QuickBooks from resolving the server's IP address.
Third-party Security Software Blocking Connection – Antivirus or firewall software might block QuickBooks connections.
Risks of Ignoring QuickBooks Error H202
While the error itself doesn't delete your data, the longer you leave it unresolved, the higher the chance of data inconsistencies, incomplete transactions, and access errors. Here are some dangers of ignoring the issue:
Inability to access or update the company file
Risk of data corruption if force-saved improperly
Disrupted multi-user collaboration
Slowed down financial reporting and decision-making
Possibility of complete data loss due to unresolved communication breakdowns
That’s why it’s crucial to act fast.
Pre-checks Before You Start
Before jumping into the full fixes, complete these basic checks:
Ensure QuickBooks is updated to the latest version.
Restart all systems and the server.
Confirm network connectivity between systems.

If the issue persists, continue with the fixes below.
7 Effective Solutions to Fix QuickBooks Error H202
Let’s walk you through the top 7 solutions to resolve QuickBooks Error H202 safely and efficiently.
Fix 1: Use the QuickBooks Tool Hub
QuickBooks Tool Hub includes a built-in utility to resolve network errors like H202.
Steps:
Download and install the latest version of QuickBooks Tool Hub from the official Intuit website.
Open the Tool Hub and go to Network Issues.
Select QuickBooks Database Server Manager.
Choose your company file folder and click Start Scan.
Once completed, restart QuickBooks in multi-user mode.
Fix 2: Verify Hosting Settings
Check and correct hosting settings on both server and workstations.
On Workstations:
Open QuickBooks > File > Utilities.
If you see “Host Multi-User Access,” do nothing.
If you see “Stop Hosting Multi-User Access,” click it to disable hosting on that workstation.
On Server:
Go to File > Utilities.
Ensure “Host Multi-User Access” is enabled.
Fix 3: Create a New .ND File
The .ND file helps QuickBooks locate company files over the network. A corrupt .ND file can trigger H202.
Steps:
Close QuickBooks on all systems.
Navigate to the folder where your company file is stored.
Locate and rename the .ND file (e.g., CompanyFile.qbw.nd → CompanyFile.qbw.nd.old).
Open QuickBooks and try accessing the company file again.
Fix 4: Configure Windows Firewall Settings
Improper firewall settings can block QuickBooks communication.
Steps:
Open Control Panel > System and Security > Windows Defender Firewall.
Select Advanced Settings > Inbound Rules > New Rule.
Choose Port, and click Next.
Add the ports used by QuickBooks:
QuickBooks 2024: 8019, XXXXX (dynamic)
(Adjust depending on your version)
Allow the connection and name the rule.
Repeat the same for Outbound Rules.
Fix 5: Edit the Windows Hosts File
Update the hosts file to map the server’s IP address to its name.
Steps:
Open Notepad as administrator.
Navigate to C:\Windows\System32\drivers\etc\hosts.
Add an entry at the bottom: CopyEdit192.168.1.100 SERVERNAME
(Replace with your actual server IP and name.)
Save the file and reboot the system.
Fix 6: Ping the Server from Workstations
Check if your workstation can reach the server.
Steps:
Press Windows + R > type cmd > Enter.
Type: pgsqlCopyEditping [server name]
If the ping fails or times out, the issue is with the network connection. Reconnect or update DNS settings.
Fix 7: Reinstall QuickBooks Database Server Manager
If none of the above works, reinstall the QuickBooks Database Server Manager on the server:
Go to Control Panel > Programs and Features > Uninstall QuickBooks Database Server.
Download the latest installer from Intuit’s website.
Reinstall it and restart your system.
Re-scan the company file folder from the Tool Hub.
