Things to keep in mind before Troubleshooting:

Before you begin troubleshooting, there are a few things that you must consider:

  2. Hosting Settings: Verify the hosting settings on each workstation. Ensure that only the server is configured to host multi-user access. This is essential for smooth operation.
  3. Backup Your Company File: Before starting any troubleshooting steps it’s necessary to create a backup of your company file. This can help safeguard the data and prevent any potential loss during the troubleshooting process.

Easy Ways to Resolve the QuickBooks Error Code in H202

Before we get into learning all the troubleshooting methods, it is highly advised to log into QuickBooks as an administrator. Now once that is done, let’s move on to the methods: 

Here’s the rephrased, reworded, and reorganized version of the input text:

Method 1: Use Ping to Diagnose Network Issues

To troubleshoot the multi-user error H202, you should ping the server from each affected workstation to check the network connection.

Step 1: Enable Network Discovery

  • Open the Windows Start menu on both the server and workstations.
  • In the search bar, type “Network” and select “Network and Sharing Center” from the results.
Network and Sharing Center
  • From the menu, select “Change advanced sharing settings.”
  • In the Network Discovery and File and Printer sharing section, confirm that “Turn on network discovery” is selected.

Step 2: Get your server name from the server you are using 

  • On your server computer, open the Windows Start menu.
  • Type “Run” into the search bar and open the Run command.
  • In the Run window, type “CMD” and press the Enter key.
  • In the CMD window, type “ipconfig/all” and press the Enter key.
  • In the Windows IP Configuration section, find the Host Name. Your server name will be listed to the right of the Host Name.
Windows IP Configuration section
  • Write down or copy the hostname to a Word document for easy access.

Step 3: Test the network connectivity

To test the server, you need to return to your workstation and follow these steps. If they become too complex, you can seek assistance from an IT professional.

  • Open the Run window by pressing the Windows and R keys simultaneously on the system where you received the H202 error code.
  • Type CMD in the text box and click OK.
  • From your computer, ping your server by typing ping_server name and pressing Enter.

  • For all systems encountering the same error, the aforementioned steps can be performed.
  • If the response is sluggish or there is packet loss, then a network problem may exist and needs to be rectified.

Method 2 – Verify QuickBooks services

If the version is running on a full version of QuickBooks, then you should follow the further provided steps to start multi-user hosting mode: 

  • While you are on the server, you are supposed to open QuickBooks Desktop. 
  • Once that is done, move to File and then Utilities. 
Verify QuickBooks services
  • To proceed, select the Host multi-user access choice.

To verify the running status of QuickbooksDBXX and QBCFMonitorService on a server, follow these steps:

  • Open the Run window.
  • In the text field, type “services.msc” and click “OK.”
Open the Run window
  • In the next step, select QuickBooksDBXX.
  • Additionally, verify the Startup type to ensure it is set to Automatic.
  • If the Startup type is not set to Automatic, change it now.
  • Subsequently, check the Service status and confirm that it displays Running.

Method 3 – Add the services QuickBooksDBXX and QBCFMonitorService to the admin group

To resolve QuickBooks Error Code H202, ensure that QuickBooksDBXX and QBCFMonitorService have Windows administrative permissions on the server. If they don’t have admin privileges, grant them these permissions to potentially resolve the issue. After granting these permissions, test the accounting software in multi-user mode. If the error persists, proceed to the next troubleshooting step.

Method 4 – Configure system firewall settings

To ensure smooth communication between QuickBooks (QB) and the server, you may need to configure your system firewall settings if it’s blocking data exchange. Here are the steps:
