Learn to fix QuickBooks Desktop Error 6123.

Solution 1: Use QuickBooks File Doctor

Step 1: Install the QuickBooks tool hub.

The QuickBooks Tool Hub is used to correct common errors; close the QuickBooks program before use.

We recommend using QB tool hub on Windows 10, 64-bit.

• Close the QuickBooks application.
• Now, download the updated version of QuickBooks Tool Hub, and as of now, it is 1.6.0.8. 
• Save your download to a short file location path. You could save it to your desktop screen.

Note:- Click on the Windows Start menu, if there is no shortcut icon on the desktop, and search for QuickBooks Tool Hub. Now, open the application. 

• Open your downloaded file, QuickBooksToolHub.exe, and follow the on-screen instructions to install the application. 
• Agree to their terms and conditions. 
• After the application gets installed, double-click on the icon that would have appeared on your Windows desktop and open the tool hub.

Note:- If there is no shortcut icon on the desktop. Select the Windows Start menu and type QuickBooks Tool Hub in the search field, and open the application.

Step 2: Run QuickBooks Database Server Manager on your server using QuickBooks Tool Hub. 

For your information, the server computer is the one where the company file has been restored. At the same time, your other computers are considered workstations that are just connected to your network.

• Click on the Network Issues in your QuickBooks Tool Hub application.
• Click on the QuickBooks Database Server Manager. In case you find that QuickBooks is not on your server, it will ask you for installation.

• Click on the Start Scan in the QuickBooks Database Server Manager if you have the folder containing your company file. 
• In case you did not find it, browse the company file’s location and click on Start Scan.
• The database server manager would automatically repair your Windows firewall permissions. Click on Close once the scan is finished.
• Launch QuickBooks on each workstation where you would find QuickBooks Desktop error code H202.
• Click on File and choose Switch to Multi-user Mode.

Step 3: In the QuickBooks Tool Hub, run the file Doctor. 

• Click on Company File Issues in the tool hub.
• Click on Run QuickBooks File Doctor. 

• Now, from the drop-down menu, select your company file. If you don’t find your file, click on Browse and search for the file.
• Click on Check your Network and hit Continue. 
• Enter your QB’s admin password and click on Next.

Solution 2: You may see QuickBooks Error 6123 while restoring the company file (.qbw)

• In the situation when you are restoring your company file from a backup (.qbb).
• Move the backup file back to your local hard drive in case your file resides on the network or external storage drive. 

Note:- Do not open them from a removable drive or an online storage folder. 

• Now, continue with the steps to restore your company file. 

Restore a backup

• While restoring a backup company file, QuickBooks uses the backup to create a new company file (.qbw).
• Click on the File menu.
• Choose Open or Restore Company.
• Click on Restore a backup copy and hit Next.

• Choose Local Backup > Next.
• You can browse your PC to fetch the backup company file.
• Choose an easy-to-reach folder to save your restored company file.
• Click on Open, and to avoid overwriting the same files, you can rename the existing company file.
• Once done, click on Save. 

Solution 3: If you see Error Code 6123 while restoring a backup (.qbb) on a new PC

• Launch QuickBooks Desktop on your PC that was used to create the backup company file. 
• Open your existing/original company file only as usual.
• You need to create a portable copy of your company file. 
• Launch QuickBooks Desktop on your new PC.
• Instead of the backup, you can restore your company file using the portable copy. 

Create a portable company file

• Launch QuickBooks and log in as an admin.
• Navigate to the File menu.
• Click on Create Copy.

• Click on Portable company file and hit Next.

• Name your portable company file with a unique name.
• Select a short file path location to save your portable company file. 
• Pick somewhere that would be easy to find, like your Windows desktop.
• Once done with everything, click on Save and then OK.

Now, you have a portable company file you can put on a USB or send online. The file must look like this: [Unique company file name].qbm.

Solution 4: Rename the .ND and .TLG files

The .ND (Network Data) file helps the program manage user access and connect to a company file on a network. The .TLG (Transaction Log) file records changes made to your company file since the last backup, allowing for data recovery in case of corruption.  

You see these 6123 series errors in QuickBooks when these .ND and .TLG get damaged. And, if you rename these files, you would not lose any data. These files get created again when you scan them with QuickBooks Database Server Manager. 

• Open the folder where you stored your company file.
• Search for the files with a similar name to your company files with the extension .ND and TLG.
  • company_file.qbw.nd
  • company_file.qbw.tlg
• Right-click on each company file and click on Rename. 
• Add an extension OLD at the end (for example: company_file.qbw.nd.OLD).
• Launch QuickBooks again and log in to your company file.

If the QB error code 6123 occurs again, try the next solution.
