Be sure about the following arrangements before you start:

  • Turn On the Network Discovery

    • Select the “System and Security” tab, and then choose the “Windows Firewall” icon.
    • In the left section, choose the “Allow an app or feature” icon via Windows Firewall (in the Windows Server 2012).
    • Choose the “Change Settings” option.
    • Click on the “Network Discovery” tab, and then choose the “OK” icon.
  • Identify the server name
    • Hit the “Windows + R” key to open/access a run command. Later, type in the “CMD”, and then click on the “Enter” tab.
    • Type in the “ipconfig /all”, and then hit the “Enter” tab.
    • In the “IP Configuration” field, search the line “Host Name” tab.
    • On the right side of the screen, you will see the server name.

If the path to your company file is on your network and begins with a drive letter, it’s a mapped drive.
  • Utilize the UNC path to spot the QB company file within the QuickBooks application. You can also search it at the title bar when clicking the mapped drive, or:
    • Hold the “Windows + R” key to access/open the run command. Later, type in the “CMD”, and then hit the “Enter” tab.
    • Enter net use [drive letter:]. For example net use z:
