Fix 10:  Change ND and TLG File Names

If you’re getting QuickBooks error 6000 80, you should check the QuickBooks support files, namely Network Descriptor (.nd) and Transaction Log (.tlg) files. If these files are corrupt, you might encounter the error 6000 80 in QB. So, rename them and ensure QB recreates these files to resolve the error 6000 80:



1. Navigate to the directory where you have stored the company files.
2. Identify files with extensions such as .ND and .TLG that correspond to your company file name (e.g., ZXYCompany.qbw.nd, ZXYCompany.qbw.tlg).
3. For each identified file, right-click, hit “Rename,” and add .OLD at the end (e.g., ZXYCompany.qbw.nd.old, ZXYCompany.qbw.tlg.old).
4. Reopen QuickBooks and attempt to open your company file. If the issue persists, proceed to the next solution to address QuickBooks error 6000 80.

Fix 11: Configure the Hosting Settings

Ensure your workstation PCs don’t host the company file because only the server has the authority to do so. So, check the hosting settings in QuickBooks on the workstation PC:

You can also choose to turn off hosting on the server until the error is fixed as follows:



1. Click File, then Utilities.
2. Select Stop Hosting Multi-User Access.

Fix 12: Change the Company File Location

If the company file is on a network drive, attempt relocating it to a local drive and then open it from there. The location where the company file is saved can be damaged, triggering the 6000 80 error in QuickBooks. You can undertake file relocation as follows:



1. Access your company file from where you have saved it.
2. Right-click the file and hit Copy or press Ctrl + C.
3. Now, access This PC > D or E drive.
4. Press Ctrl + V or right-click, then Paste the company file.
5. Open the QuickBooks company file from this location.
6. If the file launches successfully, you can make the new drive the permanent location for the folder.
7. If this doesn’t work, your QuickBooks company file might be damaged.

Fix 13: Look into the File Permissions

If the directory where your file is stored lacks the correct permissions, you might encounter QuickBooks error code 6000 80. To address this issue leading to company file inaccessibility, adjust the folder permissions with the following steps:



1. Open File Explorer by hitting the Windows logo and accessing the Windows Start menu.
2. Right-click on the folder containing the company files and go with the Properties option.
3. Choose Security, then proceed to the Advanced button.
4. Select QBDataServiceUserXX and access the Edit button.
5. Click Allow to provide the following permissions:
   • Write Extended Attributes
   • Read Attributes
   • List Folder/Read Data
   • Create Files/Write Data
   • Read Extended Attributes
   • Write Attributes
   • Read Permissions
   • Create Folders/Append Data
   • Traverse Folder/Execute File

If your permissions are configured incorrectly:

1. Right-click the Company File Folder > and hit Properties.
2. Access Security, then hit the Edit option.
3. Tap QBDataServiceUserXX, select Full Control, and then proceed with the Allow option.
4. Click Apply and OK.
5. Try opening your file and verify if the error 6000 80 persists.

Fix 14: Use the UNC Path

Instead of utilizing a mapped drive, open the company file using a UNC path (for example, \server\companyfolder\company_file.qbw). This can help you with QB error 6000 80 as follows:

1. Right-click on the QuickBooks icon on your desktop and, while holding the Ctrl key, choose ‘Run as Administrator.’ Continue holding Ctrl until the ‘No Company Open’ window is displayed to avoid the automatic opening of a company file.
2. Go to the File menu, select ‘Open or Restore Company,‘ then choose ‘Open a company file,‘ and click ‘Next.’
3. Access the left pane, click ‘Network,’ and navigate to the directory containing your company file. If you encounter difficulty finding the folder with the company file, consider adjusting folder permissions.
4. Once you find the company file, choose it and click ‘Open.’

Fix 15: Turn off Third-Party Security Software

If you have a third-party firewall or security application blocking QuickBooks access and causing the company file error 6000 80, disable it in Windows as follows:

1. Click the Windows logo for the Start menu to pop up.
2. Type Control Panel, press Enter, and open it to use.
3. Access the Windows Firewall section.
4. Choose Turn Windows Firewall On/ Off.
5. Click Disable The Firewall.

Fix 16: Restore a Recent Backup

If your company file is corrupted, you need to restore a recent backup and resolve the error 6000 80:

1. Launch the QuickBooks program and move to the File menu.
2. From the list under File, choose Open or Restore Company.
3. Hit Restore a backup copy and click Next.
4. Choose the Local Backup option and proceed with Next.
5. Click browse for your computer to locate the backup company file, typically named ZXYCompany.qbb.
6. Select a folder to save the restored company file and click Open. Caution: Be careful to avoid the risk of data overwriting if the backup is stored in the same folder as your existing company file.
7. To prevent overwriting, consider renaming either the existing company file or the backup, ensuring distinct names. Alternatively, save the backup in a new folder.
8. Once the backup file is good to go, click Save.
9. If you encounter prompts about potential data overwriting, choose the option that suits your choices, making sure to prevent unintended overwrites.
10. Your newly restored company file is now available for you to use.
