How to Fix QuickBooks Error -6000
Follow these solutions step-by-step to resolve the error:
1. Use the QuickBooks File Doctor Tool
QuickBooks File Doctor is a built-in tool that repairs company file and network issues.
-
Download and install the QuickBooks Tool Hub from the Intuit website.
-
Open Tool Hub and click on Company File Issues.
-
Select Run QuickBooks File Doctor.
-
Choose your company file and let the tool run.
Once complete, try opening your file again.
2. Rename .ND and .TLG Files
These configuration files can become corrupted.
-
Navigate to the folder containing your company file.
-
Locate files with the same name as your company file but with .ND and .TLG extensions. Example:
-
yourcompanyfile.qbw.nd -
yourcompanyfile.qbw.tlg
-
-
Right-click each and choose Rename. Add “.old” to the end of each file name.
Open QuickBooks again and try accessing the file.
3. Turn Off Hosting on Workstations
Only the server should host the company file.
-
Open QuickBooks on all workstations.
-
Go to File > Utilities.
-
If you see Stop Hosting Multi-User Access, click it. (If it says Host Multi-User Access, leave it.)
Do this on every workstation except the server.
4. Check Folder Permissions
Make sure the folder containing your company file has proper read/write permissions.
-
Right-click the folder where your company file is stored.
-
Select Properties > Security.
-
Ensure users like “Everyone” or “QBDataServiceUserXX” have full control.
5. Move the File to a Local Drive
To test if the problem is related to networking:
-
Copy the company file from the server to your desktop.
-
Open QuickBooks and select Open or restore an existing company file.
-
Browse to the copied file and open it.
If it opens successfully, the problem may be with your network or server permissions.
Pro Tip: Regularly Back Up Your Company File
Always keep a backup of your company file to avoid data loss in case of file damage or corruption.
