Reasons that User is Unable to Run QuickBooks in Multi-user Mode

1. QuickBooks is not installed on the server computer. QuickBooks comes in two versions, and you can choose to just install the version that is meant to host the company file or the one that has all the features of QuickBooks. If you are planning to host the file and also use QuickBooks on the server, you must install the full version of it.
2. Windows firewall or antivirus software is not allowing communication between user computers. Windows Firewall sometimes prevents QuickBooks from connecting to the server computer treating the connection as a security threat, and to avoid this, you need to make some changes in the firewall or antivirus settings.
3. The QuickBooks Database Server Manager is unable to access your QuickBooks company file.
4. Windows file permissions are not properly set, which leads to issues like the user being unable to run QuickBooks in multi-user mode.
5. Incorrect hosting settings of the QuickBooks Desktop application on the server that is hosting the company file. When the QuickBooks installed on the server is not running in multi-user mode or one or more systems connected to the server are set to host the company file, then also you can face issues accessing the company file in multi-user mode.
6. The DNS settings are either corrupt or incorrect.

Steps to Fix Issue when QuickBooks Keeps Opening in Single-user Mode

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 force 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.
