What Is the Connection Diagnostic Tool and How Do I Use It?

The QuickBooks Connection Diagnostic Tool is a program to troubleshoot errors you might receive when opening a QuickBooks company file (.qbw) in a multi-user environment.

It only works with QuickBooks 2008 or newer and Enterprise Solutions 8.0 or newer.

It’s designed to troubleshoot error codes H202, H505, and 6000 series errors, such as error code -6130,0.

You can download the QuickBooks Connection Diagnostic Tool directly from Intuit. Once installed on the same computer on which the company file is located, the tool can diagnose and, in some cases, repair connection problems.
