Steps to Implement when QuickBooks Keeps Opening in Single-user Mode (QuickBooks Multi-User Error)

Before you begin resolving this error, download QB File Doctor and QuickBooks Database Server Manager of the same version as QB.

Solution 1: Renaming the *.TLG and the *.ND Files

.ND and .TLG are the network data and transaction log files in QuickBooks, respectively, that help QuickBooks connect and open the company file. Damage in any of these files can trigger issues accessing the company file in QuickBooks, and thus renaming these files forces QuickBooks to create new ones that are free from any corruption and damage.

  1. Before renaming the .TLG and .ND files; here are the steps to help you locate them-
  2. Open the QuickBooks Desktop Company File.
  3. While on the Home page, press the F2 key.
  4. The Product Information window opens up. Under File Information, you will find the location of the Company File. The .TLG and .QBW.ND files are found in the same folder.
