Learn what Error H202 and H505 are and what to do if you see them in QuickBooks Desktop.
If you see Error H202 or H505 (or H101 and H103) when trying to switch into multi-user mode, we’re here to help. These errors mean something is blocking the multi-user connection to your server. We'll show you how to fix the issue.
If you haven’t already, follow the steps to install QuickBooks Database Server Manager on your server for each version of QuickBooks you use. Your server is the computer that hosts your company files. After you install Database Server Manager, continue with the sections below.
There are two ways to set up QuickBooks Database Server Manager:
Follow these steps if you use Windows Server 2012 Essentials R2, to host your network. Don’t continue with the sections below.
If you use another solution like Right Networks or one of our affiliated Intuit Hosting Providers, contact them directly for help restarting your hosting environment. You’ll need to work with them as you troubleshoot.
|Important: Devices like Network Attached Storage (NAS) don’t support the Database Server Manager.|
The QuickBooks Tool Hub helps fix common errors.
Note: If you can't find the icon, do a search in Windows for QuickBooks Tool Hub and select the program.
Your server computer is the one that stores your QuickBooks company file(s). Your other computers connected to your network are your workstations.
If your workstations can go into multi-user mode without any issues, everything is fixed.
If you still see Error H202, move on to Step 4.
|Important for the Full Program option: If you use the full version of QuickBooks on your server computer, start by turning on multi-user hosting.
Make sure QuickBooks services are running on your server computer. Follow these steps to check QuickbooksDBXX. Then repeat them for QBCFMonitorService.
When you’re done, open QuickBooks on each workstation. Go to the File menu and select Switch to Multi-user Mode. If everything opens correctly, the problem is fixed.
If you still see Error H202, move on to Step 5.
If you haven’t already, give QuickBooksDBXX and QBCFMonitorService admin permissions on your server computer. See set Windows access permissions to share company file for detailed instructions.
When you’re done, open QuickBooks on your server computer and workstations. If you still see Error H202, move on to Step 6.
Make sure your server computer is set to allow QuickBooks through your firewall.
If everything works properly, you fixed the issue. If you still see Error H202, move on to Step 7.
Ping your server from a workstation to check the connection. Ping your server from each workstation getting Error H202.
Start by turning on Network Discovery on your server computer and any workstations getting Error H202:
Next, get your server name from your server:
Go back to your workstation to test the server. These steps can get complicated, so you may want to reach out to an IT professional for assistance.
If you get a reply for each packet with no loss, your server is working fine. Move on to Step 7.
If there’s packet loss or a very slow reply, stop troubleshooting. Reach out to a qualified IT professional for help diagnosing your network.
See edit Windows hosts file for detailed instructions.
When you’re done, open QuickBooks on your workstations. If everything opens correctly, the problem is fixed.
If you see Error H101, H303, or H505, one or more of your workstations is set to be the server for QuickBooks. Your server (the computer that hosts your company files) should be the only computer set to host multi-user mode.
The Host Multi-User Access option should be turned off on your workstations. These are the computers connected to your network that don’t host your company files. Your server computer should be the only one hosting.
|Note: You can do these steps before opening a company file.|
After you check your workstations, move on to your server computer. This is the computer that normally hosts your company files.
