Method 5: Host Multi-User Access

Ensure your server runs in Multi-User mode and your workstations are in Single-User mode to resolve connection errors.

Host Multi-User Access

1. Configure Workstations:

– On each workstation (excluding the hosting computer), open QuickBooks.

– Click on the “File” menu and select “Utilities.”

2. Check Multi-User Access:

– Look for the option “Host Multi-User Access” in the list.

Method 6: Check the Portable Drive

While it is generally recommended to store your company file on a local drive, you may choose to use a portable device, such as a USB drive or external hard disk. If you decide to do so, please proceed with caution and be aware of the risks involved.

If your company file is stored on an external storage device, ensure the drive is correctly connected and operational. Additionally, consider the following points to avoid issues when accessing the file from a portable drive:

1. Properly insert the removable device. You can try:

– Disconnecting and reconnecting your drive.

– Locating your QuickBooks company file on your removable drive via My Computer.

– Saving other files to the drive to ensure it is functioning correctly.

2. Verify that your drive has sufficient available space. It should have at least double the free space of your company file size.

Method 7: Check Your Network

If your company file is stored in a network folder, you need to ensure that your system has access to that specific folder on the network drive. Follow these steps to verify access:

Open or save another company file on the server to confirm you have the necessary access.
Try creating and deleting Microsoft Excel or WordPad files in the network folder.
If you cannot create and delete a non-QuickBooks file in that folder, set up the Windows access permissions required for QuickBooks.

Method 9: Employ Verify and Rebuild Data Utility

Should the QuickBooks connection error arise due to a damaged company file, utilize QuickBooks’ Verify and Rebuild Data utilities. Here’s how:

QuickBooks Verify and Rebuild Data Utility

Open QuickBooks Desktop and access the File menu.
Choose Utilities, then Verify Data.
Allow the scan to identify errors in both the application and company file.
If errors are detected during the verification scan, proceed to run the Rebuild Data utility. Return to the File menu in QuickBooks Desktop.
Select Utilities, then Rebuild Data.
Let the scan execute, rectifying any errors found in the company file.

Method 10: Reboot All Network Computers

When grappling with the QuickBooks connection loss, consider rebooting both the server and workstation computers. Often, a simple refresh can resolve the issue effectively. To proceed:

Restart the server, ensuring no other computers are connected during the process.
Similarly, restart each workstation accordingly to address the error.

Method 11: Ensure Sufficient Permissions in Multi-user Mode

When operating in multi-user mode, proper Windows permissions are essential for accessing files. Without them, you may encounter errors like the QuickBooks connection loss. To prevent this, adjust these settings. But before proceeding, consider the following:

Verify that installation directories have the requisite permissions.
If using Microsoft Windows Home edition, note that the security tab might not be visible in normal mode. Switch to safe mode:
Restart your computer and press the F8 key until the Advanced Boot window appears.
Select Safe Mode and press Enter.
Note that the QB Desktop version determines QBDataServiceUserXX. For example, QuickBooks Desktop version 2019 corresponds to QBDataServiceUser19.
Be aware that enabling multi-user access on workstations might inadvertently trigger Alternate Hosting mode, restricting other users’ access to company files.
