Thanks for getting back to me, @IH8QuikB.

I appreciate the steps you've done to get this working. I'm here to help fix the error you're having when restoring your QuickBooks backup company file.

Below are the possible reasons why you're getting this error:

• Insufficient permissions for your network server, Windows user, or QBDataServiceUserXX.
• A firewall or security software blocking QuickBooks files.
• Damage in company file or the shared folder.
• More than one computer trying to host the company file.
• How the file is accessed (Mapped Network Drive or UNC Path).
• The file extension may be .qbm or .qbw.adr.

To isolate this, you can check out this helpful article with the detailed steps on how to fix this issue: Error -6000, -83: An error occurred. Please note that the solution may depend on what you're trying to do before the error occurred.
