Solution 1: Manually Adjusting the Settings by Renaming the.ND and.TLG Files
Although these filenames and extensions may sound unfamiliar to you, they are actually a component of your QuickBooks files. They include the setup and parameters required to open the corporate file in a shared environment.
You may always expect similar errors to appear when these files become corrupt, but you can always rename them. Your data won't be lost because of this. In fact, when you utilise the QuickBooks Database server manager to rescan and when you open your company file, these files will be regenerated.
Go to the folder where your company file is located.
Look for files with the same name as company files but different extensions.
.TLG and ND. The file should have the following name: qbw.nd company file.qbw.tlg
Rename each file by using the right-click menu. After each file name, add the term OLD. An illustration like the one below would serve as one. Keep in mind that as long as you modify the file's name, adding the term old is not strictly necessary.
qbw.nd.OLD
Try reopening QuickBooks and attempting to log into your company file. If the problem persists, continue to the solutions below.
