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.
|Tip: Whenever you're troubleshooting, always sign in to your server computer as a user with admin rights|
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. This tool connects your server to your workstations and keeps your multi-user network stable.
There are two ways to set up QuickBooks Database Server Manager:
After you install Database Server Manager, continue with the sections below.
If you use Windows Server 2012 Essentials R2, follow these steps. 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 for help restarting your hosting environment. You’ll need to work with them to reboot your hosted environment as you troubleshoot.

|Important: Devices like Network Attached Storage (NAS) don’t support Database Server Manager. If you need to use a NAS or similar external storage server, see alternative setup options.|
If you see Error H202 on one or more of your workstations, there may be a firewall issue.
As a first step, run QuickBooks Database Server Manager on your server computer to fix the connection.
|Not sure which computer is your server computer?
Your server computer is the one that stores your QuickBooks company files.
Other computers connected to the network that don’t host your company files 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 3.
|Important for 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 4.
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 5.
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 6.
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 workstations can be in multi-user mode. However, your server (the computer that hosts your company files) should be the only computer set to host the mode.
Check each workstation (the other computers connected to the network that don’t host your company files) to make sure the Host Multi-User Access option is off.
|Note: You can do these steps before opening a company file.|
After you check all of your workstations, move on to your server computer.
If you continue to see Error H101, H303, or H505, contact our support team via messenger so we can help you fix the issue.
