Thanks for posting in the Community, @BD Hodge.
In most cases, this issue usually happens in QuickBooks Point of Sales (POS) when:
- Point of Sale has been installed as a client workstation instead of a server.
- Point of Sale is attempting to reconnect to the company data file.
- The POS database service manager isn't running and is unable to login your file.
- The connection to the company file has been lost.
- The company file was damaged.
- The company file was converted to a higher version of Point of Sale using a Windows XP SP2 Operating System.
Let's perform some troubleshooting steps to help isolate this. To start, please ensure to reboot your computer to refresh the operating system to its initial state and brings optimum performance. Then, log in as the windows administrator. It allows you to make any configuration changes in Windows and control your working environment.
After that, you need to restart your QuickBooks POS, create a test company file, and restore your most recent backup. The process restores your company file to the date, and the backup created.
Once done, rename the file.
- Go to the location of your Company File: C:\Users\Public\Public Documents\Intuit\QuickBooks POS 18.0\Data\"Your Company Name".
- From the Company File location, right-click the file name.
- Select Rename and enter the new file name. If you do not want to change the entire name, you may add a letter or number at the end of the name
- Open your company file in Point of Sale again.
