Solutions to Fix Error H202:

QuickBooks provides a tool called QuickBooks File Doctor, which can automatically diagnose and fix various networking issues. Follow these steps:

  1. Download and install the QuickBooks File Doctor tool from the official Intuit website.

  3. Follow the on-screen instructions to fix any identified issues.

Solution 2: Check Network Connectivity

  1. Ensure that the server and client computers are connected to the same network.
  2. Check if the hosting computer is turned on and the company file is shared properly.
  3. Verify the hosting settings by opening QuickBooks and going to File > Utilities. Ensure that the Host Multi-User Access option is selected on the hosting computer.

Solution 3: Verify Firewall and Security Software Settings

  1. Configure firewall settings to allow QuickBooks through. Add exceptions or create rules in the firewall settings to allow QuickBooks communication.

Solution 4: Recreate the Network Data (.ND) File

  3. Rename the .ND file by adding “.old” at the end (e.g., CompanyFile.qbw.ND to CompanyFile.qbw.ND.old).

Solution 5: Verify QuickBooks Services

  1. Press Windows + R on your keyboard to open the Run dialog box.
  2. Type services.msc and press Enter.
  3. Look for services related to QuickBooks (like QuickBooksDBXX or QBCFMonitorService).
