Solution 2: Rename .ND and .TLG files

.ND and .TLG are layout files that allow QuickBooks Desktop to get into the company file(s) in a network or perhaps in multi-user mode. Damaged or Corrupted .ND or .TLG files can create errors when you open your QuickBooks desktop. If you Rename these files then it will not affect the data loss because these files are automatically recreated when you open the company file or diagnose the company files using QuickBooks Database Server Manager.

  1. Open the folder which has your company file

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

  1. Get the Files with the similar file name as the company file but with extension .ND and .TLG.

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

  1. Right click on the .nd/.tlg file and Rename it by adding the word “.old” after the file extension and hit Enter.

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

Solution 3: Use UNC path instead of the mapped drive

  1. Open the options in QuickBooks by hitting right click along with pressing CTRL key on the QuickBooks icon and choose Run as administrator. Hold the CTRL key unless you have No Company Open window.

Note: Holding down the CTRL key avoid QuickBooks Desktop from Auto-opening a company file.

  1. Through the File menu, Choose Open or Restore Company > Open a company file > Next.
  2. When you look at the left pane, Click Network and go to the location of your QB company file.
  3. Choose the company file and Hit ‘Open’

Solution 4: Configure firewall and security software

You need to configure firewall and internet security settings  because you may face errors if your firewall blocks Internet access which is needed for specific QuickBooks programs or files. Make sure that you have updated your firewall to the latest release which helps you to solve this issue automatically else you have to go ahead and manually configure your firewall software. So it is recommended by us to update your Firewall.

Solution 5: Recreate the damaged folder
