Solution 1: Turn off hosting on your workstations
If you're hosting your company files over a network, make sure the Host Multi-User Access option is off on your workstations. These are computers connected to your network that don’t host your company files. Your server computer should be the only one hosting.
Open QuickBooks on one of your workstations.
Don't open your company file. Instead, select the File menu and hover over Utilities.
If you see the "Host Multi-User Access" option, don’t select it. Move on to the next workstation. This one isn’t causing the problem.
If Stop Hosting Multi-User Access is an option, select it.
Repeat these steps on all of your workstations.
If you still see Error -6000,-83, move on to Solution 2.
Solution 2: Use QuickBooks File Doctor
Follow the steps to download File Doctor and use it to scan your company file. Let it fix any issues it finds.
If you still see Error -6000,-83, continue on to Solution 3.
Solution 3: Restore from a backup
If you have a backup of your company file, use it to restore your company file. If you don't have one, continue on to Solution 4.
Solution 4: Manually fix Error -6000, -83
Edit your Windows hosts file
If you still have issues, you can test your network to see if it's causing the error. Go to one of your workstations and follow the steps to edit your Windows hosts file.
