General Causes of QuickBooks Error 6000 77

Understanding the causes of Error 6000 77 can help in applying the correct troubleshooting methods. Here are some of the most common triggers:

  1. Improper Folder Permissions: If the folder containing the company file doesn’t have the necessary permissions, QuickBooks might not be able to access the file.
  2. Company File Located on External Storage: Accessing company files from an external drive or a non-local source can lead to connectivity issues.
  3. Conflicts with Multi-User Environment: This error often arises in a multi-user setup where more than one user tries to host the company file.
  4. Firewall Settings: Overly restrictive firewall settings or internet security software might block communication with the server hosting the company file.
  5. Corrupted Company Files: Damage to the company file or the folder where it is stored can also trigger this error.
  6. Network Descriptor File Issues: QuickBooks creates a Network Descriptor (ND) file that stores information about the database server it uses. Corruption in this file can lead to Error 6000 77.

Troubleshooting Solutions to Fix QuickBooks Error 6000 77

Now that we understand what caused QuickBooks Error 6000 77 let’s discuss how to resolve it. Follow these steps methodically to restore access to your company files.

  1. Use the QuickBooks File Doctor Tool

QuickBooks File Doctor is a tool developed by Intuit that can automatically find and fix common errors with your QuickBooks files. Follow these steps to use it:

  • Download and install the QuickBooks Tool Hub.
  • Launch the Tool Hub and select the Company File Issues tab.
  • Click on Run QuickBooks File Doctor.
  • Choose your company file from the drop-down or browse to locate it manually.
  • Select the Check your file option and click Continue.
  • Enter your QuickBooks admin password and then click Next.
  1. Change the Location of the Company File

If the error persists, try moving the company file to a different location:

  • Navigate to the folder where the company file is stored.
  • Copy the file (with the extension .QBW) to your desktop.
  • Open QuickBooks and try to access the file directly from the desktop. If it opens, permission issues may be present at the original location.
  • After testing, move the file back to the original location and reset the folder permissions appropriately.
  1. Configure Firewall and Anti-Virus Settings

Incorrect firewall settings can prevent QuickBooks from accessing necessary network ports. Adjust your firewall settings by:

  • Ensuring that the ports 8019, 56728, 55378-55382 are accessible for the QuickBooks application.
  • Configuring the firewall to allow exceptions for QuickBooks.

4 .Recreate Damaged Network Descriptor (ND) File

Recreating the ND file can resolve network issues related to the company file:

  • Navigate to the folder containing your company file.
  • Find the file with the same name as your company file but with an.ND extension.
  • Delete this ND file.
  • Open QuickBooks and open your company file. QuickBooks will automatically recreate the ND file.
  1. Check Hosting Settings

In a multi-user environment, make sure that only one computer (usually the server) is set up to host the company files:

  • On each workstation (not the server), open QuickBooks and go to File > Utilities.
  • If you see the Host Multi-User Access option, don’t select it. This means this computer is not hosting the company file.
  • If you see Stop Hosting Multi-User Access, select it to turn off hosting on this computer.
  1. Use QuickBooks Database Server Manager

If your company file is stored on a server, use the QuickBooks Database Server Manager on the server to rescan the company file:

  • Open the QuickBooks Tool Hub on the server.
  • Go to the Network Issues tab and select QuickBooks Database Server Manager.
  • Inside the Database Server Manager, add the folder containing your company files and start the scan.
  • The Database Server Manager will repair the permissions automatically to allow for correct access.


QuickBooks Error 6000 77 can be frustrating, but with the right knowledge and tools, it is typically something you can resolve on your own. By understanding the common causes and following the detailed troubleshooting steps outlined above, you can restore your QuickBooks operations and ensure your financial data remains secure and accessible.
