Let's work together and get to the bottom of your QuickBooks Desktop Database Sever Manager concern, @bschoolm. I appreciate the troubleshooting you did and recognize the importance using multiuser.
As a workaround, I suggest uninstalling the version that was set up on the server PC. After uninstalling the previous version, if the QuickBooks Server Manager version 2022 cannot be located, you can fix it by manually doing a clean install of QuickBooks 2022.
to ensure you'll get an update about the resolution status, I recommend contacting our QuickBooks Support Team. Our Support Team is available every Monday to Friday 6 AM – 6 PM Pacific Standard Time (PST) and on a Saturday at 6 AM – 3 PM PST.
You'll see the detailed instructions on this from the article I'm attaching below (scroll down to If you're trying to update QuickBooks Database Server Manager on the server computer): QuickBooks Database Manager.
