4. Rename .ND and .TLG files

.ND and .TLG are the configuration files that enable QuickBooks Desktop to open a company file in network or multi-user mode. Possible damage or corruption to these files can cause errors when opening QuickBooks Desktop and the company file.

Renaming these files will replace them with the new ones when you open the company file or scan using the QuickBooks Database Server Manager, addressing all the associated issues.

Follow the steps below to learn how to rename .ND and .TLG files in QuickBooks:  

• Open the folder where your QuickBooks file is saved. 

Default Location: C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files

• Look for the files with the same name as your company file but with the .ND and .TLG extensions at the end. 

Example: company_file.qbw.nd, company_file.qbw.tlg

• Right-click on the .ND and .TLG files and select Rename. Now, add the .OLD after the file extension and press Enter. 

Example: company_file.qbw.nd.OLD, company_file.qbw.tlg.OLD.

Switching to a UNC path (Universal Naming Convention) bypasses the mapped drives and refers to the server location directly, potentially resolving the issue

Note: Holding down the Ctrl key prevents QuickBooks Desktop to automatically open the company file
