Quickbooks documentation did not work for me, but this did.

The Problem

In Quickbooks Enterprise 2019 I could start in Single-user mode, but if I tried to start in multi-user I could not. I ran through every single utility in the QBTool kit to no avail.

When I scanned for the company file in the QB database utility, I'd get a message the QBDBMgrN was not running. In services.msc, the two main Quickbooks services would not start even after setting them all to keep trying after all consecutive failures. I also reconstructed the file.

My firewall ports were fine.

After reading this article from Quickbooks, and trying all of the recommendations, I resorted to uninstalling the application.

This still didn't work. I kept getting the same exact error when I tried to switch to multi-user mode. I realized that I had a bunch of Quickbooks files left over even after uninstalling so I deleted all of the files in:

C:\Program Files x86\Intuit

Deleted all qb users on the server.

After reinstalling this still didn't work.

The solution:

Uninstall with Revo Uninstaller. Use the advanced scan to check the registry and nuke all of the leftover QB garbage. Then reinstall the app. Hopefully this helps someone out.
