Hi there, @danly-edmoffices.
Let me step in and assist you in fixing error H202 when you tried switching multi-user mode.
This error appears when something's blocking the connection to your server. You can follow these troubleshooting steps to fix this issue:
Step 1: Follow steps depending on how you host your company files
Hosting your own network
Install QuickBooks Database Server Manager on your server for each QuickBooks version you use. Your server is the computer that hosts your company files. After installing it, please check the two ways to set up QuickBooks Database Server Manager:
