QuickBooks Error H202: What It Means and How to Fix It (2026)
Quick Answer
Error H202 occurs when QuickBooks cannot connect to the company file on another computer in multi-user mode. The hosting configuration or firewall is blocking the connection between workstations.
What Error H202 Actually Means
QuickBooks Error H202 appears when you try to switch to multi-user mode or open a company file hosted on another computer. It means your workstation found the server but cannot communicate with the QuickBooks Database Server Manager on that machine. This is almost always a network configuration issue, not a data problem.
Common causes:
- QuickBooks Database Server Manager is not running on the host computer
- Firewall or antivirus is blocking QuickBooks ports (8019, 56728, 55378-55382)
- The hosting configuration is set incorrectly (multiple computers set to host)
- DNS resolution is failing between workstations
- Windows services required by QuickBooks have stopped
How to Fix Error H202
Verify hosting on the server
On the computer that stores the company file, open QuickBooks, go to File > Utilities, and confirm "Host Multi-User Access" is enabled. On all OTHER computers, confirm "Stop Hosting Multi-User Access" is selected.
Restart QuickBooks Database Server Manager
On the host computer, press Windows+R, type services.msc, find "QuickBooksDBXX" (where XX is your version year), right-click and Restart. Do the same for "QBCFMonitorService".
Configure firewall exceptions
Add exceptions for QBDBMgrN.exe, QBDBMgr.exe, QBW32.exe, and QBUpdate.exe in your Windows Firewall and any third-party antivirus. Also open ports 8019, 56728, and 55378-55382.
Ping the server from the workstation
Open Command Prompt on the workstation and type "ping [server-name]". If it fails, you have a network issue that is not specific to QuickBooks. Check that both computers are on the same network and subnet.
Use the QuickBooks File Doctor
Download and run the QuickBooks Tool Hub from Intuit. Select "Company File Issues" then "Run QuickBooks File Doctor". Select your company file and choose "Check your file and network".
Why Error H202 Keeps Coming Back
H202 often returns after Windows updates that reset firewall rules, after antivirus software updates that re-enable blocking, or when the host computer restarts and QuickBooks Database Server Manager does not auto-start. If you see this error repeatedly, set QBDBMgrN to "Automatic (Delayed Start)" in Windows Services and add permanent firewall rules rather than temporary exceptions.

Frequently Asked Questions
Can Error H202 cause data loss?
No. H202 is a connectivity error, not a data corruption error. Your company file is safe on the server. The workstation simply cannot reach it.
Does H202 only happen in multi-user mode?
Yes. If you are the only person using QuickBooks and your file is on your local drive, you will never see H202. It only occurs when accessing a file over a network.
Will upgrading QuickBooks fix H202?
Not necessarily. H202 is caused by network and hosting configuration, not by the QuickBooks version. However, upgrading does reset services which sometimes resolves it temporarily.
Can I use QuickBooks Online instead to avoid H202?
Yes. QuickBooks Online eliminates all multi-user hosting errors because there is no local file to host. However, migrating has its own trade-offs depending on your feature needs.
How does Hubricon help prevent H202?
Hubricon connects to QuickBooks Online via the official API, so you never deal with file hosting, multi-user conflicts, or network errors. Your financial data syncs automatically every 6 hours.
