➜QuickBooks .ND File (Network Data): This is a configuration file that enables QuickBooks Desktop to access the main Company File (.QBW) in a multi-user or network environment. It is created by the QuickBooks Database Server Manager and contains critical information for server communication, such as the server’s IP address and port used for the company file.
➜QuickBooks .TLG File (Transaction Log): This file is crucial for data recovery and integrity. It logs every change and transaction made to the Company File (.QBW) since the last successful complete backup. If your main company file becomes corrupted or damaged, Intuit data services can use the .TLG file in conjunction with your latest backup to restore lost transactions.
Since the .ND and .TLG files are critical for network access and data integrity, their corruption or incorrect configuration can trigger several errors, most notably those related to multi-user mode and file access:
➜H-Series Errors: Errors like H202, H303, or H505 typically indicate an issue preventing workstations from connecting to the company file over the network, which is often tied to a damaged or incorrect .ND file configuration or hosting issues.
➜Data Integrity Errors: Errors like -6189, 816 or when the company file simply fails to open in multi-user mode can be caused by damaged .ND or .TLG files.
.QBW), do I need to move the corresponding .ND and .TLG files?Yes, you must move all three files together to the new location. The .ND and .TLG files must reside in the exact same folder as the .QBW file they correspond to. If you move the .QBW file without its .ND and .TLG counterparts, QuickBooks will either recreate new (empty) ones in the new location or, in some cases, fail to open the file correctly, resulting in an error.
.ND and .TLG files cause loss of company data or transaction history?No. Renaming .ND or .TLG does not affect the main company file (.QBW), which holds all your actual data (accounts, transactions, payroll, etc.). The .ND and .TLG are auxiliary files QuickBooks simply regenerates fresh ones when needed. Thus, your core financial data remains intact.
You only need to rename the .ND/.TLG files located in the folder where the company file resides (usually on the server). Because .ND holds the network-related metadata (server, path, port), renaming it at the server location ensures a fresh, correct descriptor. Once recreated, all connected workstations will use that updated configuration when they connect.
