Solution 2: Rename the .ND and .TLG file

In a situation where either one or both the files are damaged, you may face issues while opening the company file.

You can consider changing the file’s name as it would have no impact on the data. These files are created again when you use the QuickBooks database server manager tool as well as open the company file.

• Go to No Company Open window, click on Select a Sample File tab and open the Sample Company File list.
