How to Fix QuickBooks Desktop ND File Error?

The QuickBooks ND File Error occurs often in multi-user setups. The .ND (Network Data) file is essential for QuickBooks Desktop to connect to the company file over a network. The QuickBooks Database Server Manager creates this file and contains network details like the IP address and port needed to connect to the server. If this file is damaged, deleted, or misconfigured, QuickBooks may not find the company file, causing connection issues, especially in multi-user mode.It is usually caused by a broken network setup, incorrect folder permissions, conflicts with firewall or antivirus software, or an issue with the Database Server Manager.

 To fix the error, rename the .ND file, rescan the folder using the QuickBooks Database Server Manager, check folder and firewall settings, and make sure only one system is hosting the company file. Regular maintenance can help prevent these errors and keep your workflow smooth. In below, we have mentioned 2 methods to fix QuickBooks Desktop ND File Error.
