How to Fix QuickBooks Error H202

Resolving QuickBooks Error H202 involves several steps. Below are detailed solutions:

   • Right-click on each service, select "Properties", and ensure the startup type is set to "Automatic".
   • If the services are not running, click "Start" to begin the service.

6. Ping the Server:

   • Open the Command Prompt on a workstation and type "ping [server name]" (replace [server name] with the name of your server).

   • If there are issues, it may indicate network problems that need to be addressed.

7. Use QuickBooks File Doctor:
