Solution 1 – Rename the QB Transaction Log and Network Data Files

If essential configuration files, like the Transaction Log and Network Data files, are damaged/corrupted, it can lead to errors like 6129 in QuickBooks.

2. Next, reboot your PC, open the Windows Start menu, and type “Control Panel” in the search box.

If you face issues while restoring the company file backup, perform the following steps –

2. If yes, select this option to disable the hosting and click Yes in the Stop Hosting Multi-User Access window.
