QuickBooks users often report receiving error code H202 when switching to multi-user mode. A blocked multi-user connection to your server computer, which stores QuickBooks company files (QBW), usually causes this error. The QuickBooks company file cannot be accessed if you cannot communicate with the server computer.
How does QuickBooks Error H202 occur?
QuickBooks company files (QBW) are stored on a server computer on a multi-user network. An H202 QuickBooks error occurs when a workstation is unable to access a company file on another computer.
Why does QuickBooks Error H202 occur?
A quickbooks error code h202 occurs when QuickBooks Desktop is trying to connect to the company file, but can’t communicate with the server for one of the following reasons:
- Configuration settings for the hosting server are incorrect.
- Incoming and outgoing communications are being blocked by the server computer firewall.
- DNS server conflict.
- There is a problem with QuickBooks getting the IP address of the server hosting the company file.
- QuickBooksDBXX and QBCFMonitor, some internal QuickBooks services, aren’t running on the server.
- A corrupt or damaged network data file (.ND) has been detected.
What can be done to fix QuickBooks Error H202?
Be sure to back up your QBW file before attempting the solutions in this section. You will be able to restore the original data if you do so.
QuickBooks Database Server Manager can be used to fix the error, according to Intuit. If you’ve already tried that, and you’re still getting H202 error, try these solutions:
Note: For best results, implement the solutions in the following order.
Solution 1 – Test Network Connectivity
Check your network connection by pinging your server from the workstation receiving error H202.
You will need to turn on “Network Discovery” on your server computer and any workstation that receives the error if you do not know your server’s name.
Ping your server by following these steps:
- Open the Run window by typing run into the Windows search bar.
- Click Run, and type cmd into the search box.
- From your workstation, enter ping [servername] to ping the server name.
When you detect packet loss or get a slow response, the network needs to be repaired.
Solution 2 – Use QuickBooks File Doctor
To resolve network issues that might be preventing multi-user connections to QuickBooks, run the quickbooks file doctor Tool.
Try the next solution if QuickBooks error H202 persists.
Solution 3 – Setup QuickBooks Desktop’s firewall
Make sure the firewall settings on the server computer aren’t blocking QuickBooks. For detailed instructions on adding QuickBooks ports exceptions to the firewall, see the post ‘Configure Firewall and Internet Security Settings for QuickBooks Desktop’.
After setting firewall permissions, open QuickBooks in multi-user mode on your workstation. Check out the next solution if the problem persists.
Solution 4 – Ensure QuickBooks services are running
Make sure QuickBooks is running on the server computer. Check if Quickbooks DBXX services are running, then repeat the steps for QBCFMonitorService.
- Run can be found by typing Run into the Windows search bar.
- Enter services.msc in the Run window.
- Double-click QuickBooksDBXX in the Services window.
- The QuickBooksDBXX Properties window appears. Choose Automatic as the startup type.
- Service status must be set to Running or Started. Otherwise, select Start.
- Select the Recovery tab next.
- From all three drop-down menus: First failure, Second failure, and Subsequent failures, select Restart the Service.
- Click on Apply and then OK
Follow the same steps for QBCFMonitorService. After completing the steps, open QuickBooks on each workstation. Select Switch to Multi-user Mode from the File menu. The problem is solved if you can open everything correctly.
Solution 5 – Make a new folder for your QBW files
Next, create a new folder for your QBW file:
- Create a new folder, On the server computer,
- Set up Windows access permissions to share company files by sharing the folder.
- The QuickBooks Database (QBW) file should be copied to the new folder.
- Reopen your company file in multi-user mode.
