Reasons

Solutions

Some of the effective methods to resolve this hosting error in QuickBooks are mentioned below-


Solution 1- Fix QuickBooks hosting settings on the server computer and workstations

This error code is displayed on the screen when QuickBooks fails to establish a multi-user network due to incorrect hosting settings. You’ll be able to access/host your company file only when the server computer uses the multi-user mode and all the workstations run in single-user mode. If workstations start using multi-user mode, none of the systems will be able to access the file, and you’ll see this error code on the screen. A way to fix the error is by configuring the hosting settings in your QuickBooks as shown below-

  1. On the workstations where this error is displayed, launch QuickBooks and go to the File menu.
  2. Select Utilities and tap Stop hosting multi-user access.
  3. Convert all workstations to single-user mode using the same steps.
  4. Go to the QuickBooks File menu on your server computer and select Utilities.
  5. Click on Host Multi-User Access and save the settings.
  6. Reboot all systems, including the server computer.
  7. When the server computer reopens, open the company file on your QuickBooks in multi-user mode.


Solution 2- Use QuickBooks in Administrator mode

This error can also develop when QuickBooks fails to connect to other systems in the network due to interruptions of other applications or restrictions of the firewall. You can prevent the issue from recurring by using the software in Administrator mode, as shown in the following steps-

  1. Open the QuickBooks folder using File Explorer.
  2. Right-click on its launch icon and select Properties.
  3. Mark the Run this program as administrator checkbox under the Compatibility tab.
  4. Save the settings and rerun QuickBooks.

The multi-user mode issue will disappear, and you can work on your company file without problems now.
