Errors which may occur during the process

Data Synchronize Errors

Data Synchronize errors mean there is a problem in your data and due to this reason you are not seeing your full data meanwhile your transactions are lost which were previously present in QB. Vendor, Item or Customer lists show fewer items than it was before so the type of errors you are facing called Data-sync errors. These errors occur when “QuickBooks Sync Manager” is not syncing your company file data and that’s why you’re facing data loss. You can contact our QuickBooks Error Support team member they will provide you with a relevant solution.

Network Diagnosis

The first thing that you must be logged in as Administrator in Windows and Windows User Account control must be turned off. And logged in with all administrative privileges into the windows than QuickBooks file doctor will turn off the UAC by itself.

You must be looking into these steps if QBFD is giving you errors like UAC is turned on, Search “User Account Control Settings” in the search bar of the start menu and Open “User Account Control Settings”. You will see this:

Quickbooks Network Diagnosis

If there are multiple versions installed into the system then QB File Doctor is unable to troubleshoot the problem. So, it is the biggest limitation that user will face, when he is using multiple version in that case you must take your file to another system where there is only one version is installed.

This is the biggest issue that is still present in QBFD and is the biggest barrier for a lot of entrepreneurs to use File Doctor. After this situation as previous tools are not available in the market right now and are not compatible with new versions of the QuickBooks so there is only one possibility that business-facing problems should upload the file to “Intuit Data services”.

The Network Diagnosis is started by default you can change the default settings and can stop the Data issues diagnosis. If you want the QBFD to resolve only networking issues. When you launch the application you will see the advanced settings in the first window.
