QuickBooks Error 6000 83 typically occurs when QuickBooks is unable to open your company file due to network-related issues or damage to the company file itself. To troubleshoot this error, start by checking your network connection and ensuring that all systems are properly connected. If you are using a multi-user setup, make sure all computers are connected to the server correctly. You should also run the QuickBooks File Doctor to repair any potential file damage.
