(Note: If you cannot rename the file, try saving the file to another location.)

The first step for this condition is opening a sample company file and recognizing whether it is a file-related issue. Move to the steps given steps, once the company file issue is verified.

Please note, 

• The following steps might require Admin rights to the computer.
• QuickBooks must be up-to-date.

Solution 1: Disable Antivirus and other Software 

• Restart the computer on “Windows Safe Mode.”
• Disable any active antivirus on the computer.
• Open QuickBooks and add a new company file. 
• Restart the computer in normal mode. 
• Open the QuickBooks company file again and check its proper functioning. 

Solution 2: Rename QuickBooks Network (.ND) Files 

• Open File manager and go to C-drive (default drive for installed programs). 
• Click on the QuickBooks folder files. 
• Check for files with the “.nd” extension. 
• Go to the “.nd” files, rename all the files, and add “.OLD” on all network files. 

If you use QuickBooks in multi-user mode, rename network files for all individual devices. 

• Open the QuickBooks Database server manager and click on “Scan Folders.”
• Click “Add new folder” on the QuickBooks database server manager if you do not find the company file after the scan.  
• Once you have completed all the steps, open the company file and check whether it is properly functioning. 

Solution 3: Change the company file location

Changing the company file location to a new folder is easier for single users, who can just “add a new folder” and move all the company files to that location. 

Users using QuickBooks in multi-user mode are required to follow additional steps to change a company file location. Here is how to change company location in multi-user mode:

• Open QuickBooks Database Server manager. 
• Click on the “Scan Folder” option.
• Click on “Add a new folder.” 

(Note: Click on “Add new folder” if a folder you do not find any folder at the time of the scan.)

You will be able to find the desired file from the mentioned steps. Once you find the file after a scan, change the location of your company file. 

Solution 4: Check whether all computers are on a single Domain

Domains are vital to all the connections on the internet. The QuickBooks 6000 series error can also occur because the connected computers are not on a common Domain. Ask your IT team or contact a networking expert to connect all the computers on a single domain. 

Solution 5: Run file doctor

• Download and install the QuickBooks tool hub.
• Go to “Company file issue” on your QuickBooks tool hub and run QuickBooks file doctor.
• Once the process is complete, look for any errors on the company file. 
• Try running the company file once the repair is complete. 

Solution 6: Update QuickBooks software

Many QuickBooks errors occur because of outdated software running on the system. Updating the software provides better security and helps avoid compatibility issues that cause common QB errors.
