Can you open the sample file in multiuser mode?

To restore your network connection, ensure the QuickBooks Database Server Manager is active on the host computer. Also, confirm that all computers are connected to the same network. Then use the Automated Password Reset tool to regain login access.

Here are the troubleshooting steps that we can perform:

First, check the folder permissions on your server computer to ensure the folder holding your company files is shared on your network.

Second, make sure that the QuickBooks Database Server Manager is installed on your server computer. This will allow you to share your company files with other computers on the network.

Next, set the Windows admin rights. This will let you change your firewall settings and folder permissions.

Then, scan your folder using the Database Server Manager to access your file over the network.

Lastly, turn on hosting on your server computer:

1. Go to the File menu and select Utilities.
2. Then, choose Host Multi-User Access and click Yes to confirm.

After completing the process, open QuickBooks on another workstation to confirm you can successfully access the company file in multi-user mode.
