Thanks for checking in with us, jk8. 

If you are referring to Multi-User errors after upgrading to QuickBooks 2022 caused by the missing Database Server Manager, then this investigation under INV-63789 was already fixed. If you've already installed QuickBooks 2022, make sure to get the latest release. Then, run QuickBooks Database Server Manager and ensure all of your workstations are working. 

If you encounter an issue, we can perform these on the main server or the computer where QuickBooks and the company files are saved. First, let's disable multi-user access. Here's how:

1. Access your QuickBooks company file as the Admin.
2. Go to the File menu.
3. Select Utilities.
4. If Stop Hosting Multi-User Access is listed, choose Stop Hosting Multi-User Access.  

Then, create a backup copy of your company file. Once done, download and install QuickBooks Tools Hub and run the Quick Fix my Program. This built-in tool auto-detects and auto-fix data damage issues within the software. Let me show you how: 

1. Download the most recent version (1.4.0.0) of the QuickBooks Tool Hub.
2. Locate the file you downloaded (QuickBooksToolHub.exe).
3. Follow the on-screen steps to install and agree to the terms and conditions.
4. From the tool hub, click Company File Issues.
5. Choose Quick Fix my File.
6. Press OK when it completes and launch your QuickBooks.

Once completed, restart QuickBooks to ensure that all components are updated. Then, start updating your software by following the steps below: 

1. Open QuickBooks.
2. Choose the Help menu.
3. Select Update QuickBooks.
4. From the Update Now tab, click the Get Updates button

If the issue persists, just proceed to Steps 3 and 4 from this article: Fix company file and network issues with QuickBooks File Doctor. To learn more about utilizing the security setting, hosting providers, and the multi-user setup, please scan through these resources:
