QuickBooks is a go-to accounting software for small and medium-sized businesses that rely on seamless collaboration. When multiple users attempt to access the company file simultaneously, QuickBooks Error H202 can suddenly appear, halting work and causing frustration. This issue occurs when QuickBooks Desktop struggles to connect with the company file stored on another computer (the server).
If you’ve run into QuickBooks Error H202 and can’t switch to multi-user mode, you’re in the right place. This detailed guide explains why it happens, how to fix it step-by-step, and how you can get direct assistance at +1-866-408-0444 to get your QuickBooks running smoothly again.
What Is QuickBooks Error H202?
QuickBooks Error H202 typically occurs when the workstation—one of the computers connected to the company file—fails to connect to the file hosted on the server system. In other words, QuickBooks thinks the company file is located on another computer, but communication is blocked by network configuration issues or service interruptions.
The error message usually says:“ This company file is on another computer, and QuickBooks needs some help connecting.”
When that appears, it’s a sign that QuickBooks can’t reach the server that stores your files.
Why QuickBooks Error H202 Happens
Understanding the cause is key before jumping into fixes. The error may stem from:
Incorrect hosting configuration on workstations.
Blocked or inactive QuickBooks Database Server Manager (QBDBMgrN).
Damaged or missing DNS settings.
Firewall blocking incoming/outgoing communication between systems.
Inactive QuickBooks services on the host computer.
Regardless of what’s causing it, Error H202 can disrupt your business operations. But don’t worry—you can fix it quickly using the steps below or by calling +1-866-408-0444 for guided troubleshooting.
Step-by-Step Solutions to Fix QuickBooks Error H202
Step 1: Run the QuickBooks File Doctor
The QuickBooks File Doctor is an official tool designed by Intuit to resolve common network and company file issues automatically.
Download and install the QuickBooks Tool Hub (latest version).
Open it and select Company File Issues.
Run the QuickBooks File Doctor and choose your company file.
Wait for it to diagnose and repair connectivity errors.
Once completed, open QuickBooks in multi-user mode again. If the error persists, continue with the next fix.
Step 2: Verify Hosting Settings
Hosting configuration is essential for multi-user access. Only the server computer should host the company file.
On each workstation, open QuickBooks.
Go to File > Utilities.
If you see “Host Multi-User Access,” do not select it. It means your workstation isn’t hosting—perfect.
If you see “Stop Hosting Multi-User Access,” select it to disable hosting on that machine.
After verifying, restart all systems and try switching to multi-user mode again.
Step 3: Check QuickBooks Services
Two essential services—QuickBooksDBXX (where XX represents the version year) and QBCFMonitorService—must be running on the host computer.
Press Windows + R and type services.msc.
Locate both services on the list.
Ensure both are set to Automatic and Running.
If they’re not, right-click each one, select Start, and set the startup type to Automatic.
Restart QuickBooks to check if the communication issue is resolved.
Step 4: Configure Windows Firewall
Firewalls often block the data exchange required by QuickBooks. Adding specific inbound and outbound rules can help restore communication.
Open Windows Firewall settings.
Click Advanced Settings > Inbound Rules > New Rule.
Choose Port and add ports for your QuickBooks version (for example, 8019, and other dynamically assigned ports listed in QuickBooks Database Server Manager).
Repeat the same under Outbound Rules.
Save all changes and restart your system.
If this sounds complicated, you can reach out at +1-866-408-0444, and a QuickBooks expert will guide you through this process step-by-step.
Step 5: Check Network Connectivity
A broken network connection between workstations and the server can trigger Error H202.
Use the ping command: On your workstation, press Windows + R, type cmd, and enter ping [ServerName].
If the response time is slow, or packets are lost, network configuration may be at fault.
In such cases, confirm that both systems are on the same network domain and that your network hardware (routers or switches) function properly.
Step 6: Recreate the .ND File
The .ND (Network Data) file enables QuickBooks to access company files over the network. If it’s damaged, QuickBooks won’t connect to the file location.
Navigate to your company file folder.
Locate the file with the same name as your company file but ending in .ND.
Right-click and rename it (for example, CompanyFile.old.nd).
Open QuickBooks Database Server Manager and rescan the folder.
This will automatically create a new .ND file and reestablish the connection.
Additional Expert Tip
If multiple users frequently face QuickBooks Error H202, it’s a good idea to install the QuickBooks Database Server Manager separately on your host system for reliable company file hosting. Consistent maintenance of your server settings and firewall configurations also prevents future disruptions.
