Resolving H202 Error in QuickBooks Database

If you are encountering the H202 error in your QuickBooks database, do not panic. This error typically occurs when QuickBooks is unable to establish a connection to the company file located on another computer. It can be frustrating and disrupt your workflow, but there are several steps you can take to resolve this issue.

Step 1: Verify Network Connectivity

Make sure that your network allows communication and that all computers involved can access each other. Check if you can ping the server from the workstation experiencing the H202 error. If the server is unreachable, it may indicate network configuration or firewall issues that need to be addressed.

Step 2: Confirm Hosting Settings

Ensure that the server is hosting the company file and the workstations are not attempting to host it. To do this, open QuickBooks on the server and go to the "File" menu. Select "Utilities" and check if "Host Multi-User Access" is selected. If it is, proceed to the next step. If not, enable hosting on the server and restart all workstations.

Step 3: Adjust Firewall and Security Settings

Configure your firewall and security software to allow QuickBooks to communicate through the necessary ports. QuickBooks uses ports 8019, 56728, and 55378-55382 for communication. Consult the documentation of your firewall or security software to learn how to open these ports. Additionally, ensure that the .ND and .TLG files associated with your company file are not being blocked by your security software.

Step 4: Create a New Folder for Your Company File

Try creating a new folder on the server and move your company file into it. Make sure the folder has proper Windows access permissions. Then, share the newly created folder and grant full access to all users who need to access the company file. Afterward, try opening the company file from the new location on each workstation to see if the H202 error persists.

Step 5: Use the QuickBooks Database Server Manager

If none of the above steps resolve the H202 error, utilize the QuickBooks Database Server Manager to scan and repair your company file. Install the Database Server Manager on the server hosting the company file and follow the on-screen instructions to scan the company file. This can help resolve any database-related issues that may be causing the H202 error.

By following these steps, the H202 error in your QuickBooks database should be resolved, allowing you to resume your work seamlessly. However, if you continue to encounter difficulties, consider seeking assistance from QuickBooks support or consulting a professional with expertise in QuickBooks troubleshooting.
