How to Fix QuickBooks Error H202 (Step-by-Step)
Below are the most effective methods to resolve H202.
1. Use QuickBooks Database Server Manager
QuickBooks Database Server Manager helps manage the company file for multi-user access.
Steps:
Download and install QuickBooks Tool Hub (if not already installed).
Open Tool Hub → Select Network Issues.
Choose QuickBooks Database Server Manager.
Click Start Scan and select the folder containing your company file.
After scanning, restart QuickBooks and switch to multi-user mode again.
2. Verify Hosting Settings on All Computers
Make sure only the server hosts the company file.
On Workstations:
Open QuickBooks.
Go to File → Utilities.
If you see Stop Hosting Multi-User Access, click it (this disables hosting on workstations).
If you see Host Multi-User Access, leave it as is.
On Server:
Ensure Host Multi-User Access is enabled.
3. Add Windows Firewall Rules for QuickBooks
Firewalls often block multi-user connections.
Steps:
Open Control Panel → Windows Defender Firewall.
Select Advanced Settings.
Create new Inbound Rules for QuickBooks ports:
QuickBooks 2024: 8019, 56740–56745
QuickBooks 2023/2022/2021: 8019, 56728
Repeat the same for Outbound Rules.
Restart your computer and QuickBooks.
4. Ping Your Server From the Workstation
A failed ping indicates network connectivity issues.
Steps:
Press Windows + R, type CMD, press Enter.
Type:
ping SERVERNAMEIf packets drop or ping fails, fix network or DNS issues.
5. Check QuickBooks Services (QBCFMonitorService & QBDBMgrN)
These services must be running for multi-user mode.
Steps:
Press Windows + R, type services.msc.
Locate QBDBMgrN and QBCFMonitorService.
Set Startup Type to Automatic.
Click Start if the service isn’t running.
6. Rename the .ND File
The Network Data (.ND) file helps QuickBooks connect to the server.
Steps:
Go to the folder containing the company file (.QBW).
Find the related .ND file.
Right-click → Rename → Add .old to the end.
Open QuickBooks and rescan the file using Database Server Manager.
A new .ND file is automatically created.
7. Create a New Network Data Path Using UNC Path
Sometimes QuickBooks cannot read mapped drives.
Steps:
In QuickBooks, open the Open or Restore Company window.
Browsing, type:
\\SERVERNAME\SharedFolderSelect your company file and open in multi-user mode.
