What is QuickBooks Error H202?

3. Inactive QuickBooks Database Server Manager (QBDSM)

   • The QuickBooks service that allows multi-user connections isn’t running on the server.

4. Issues with QuickBooks Services

   • QuickBooksDBXX or QBCFMonitor services are stopped or malfunctioning.

5. Hosting Configuration Problems

   • Multiple computers are set as hosts, or the host computer’s settings are incorrect.

1. Open QuickBooks and go to File > Utilities.

2. If you see Stop Hosting Multi-User Access, select it.

3. If you see Host Multi-User Access, leave it as is.

On the server:

Solution 3: Configure QuickBooks Database Server Manager

The QuickBooks Database Server Manager (QBDSM) helps multiple users access the same company file simultaneously.

1. On the server, open QuickBooks Tool Hub.

2. Select Network Issues and click QuickBooks Database Server Manager.

3. Browse to your company file folder and click Start Scan.

4. Once scanning completes, try accessing the file again.

Solution 4: Adjust Firewall and Security Settings

Firewalls often block the ports required for QuickBooks multi-user mode.

Open required ports for QuickBooks:

• QuickBooks 2024: 8019, 56728, 55378–55382

• QuickBooks 2023: 8019, 56727, 55373–55377

• (Ports vary by version – confirm with your QuickBooks documentation)

Steps:

1. Go to Windows Firewall Settings.

2. Select Advanced Settings > Inbound Rules.

3. Add new rules for QuickBooks ports.

4. Repeat for Outbound Rules.

Solution 5: Check QuickBooks Services on Server

The QuickBooksDBXX (where XX is your version) and QBCFMonitorService must be running.

1. Press Windows + R, type services.msc, and press Enter.

2. Locate QuickBooksDBXX.

   • Right-click and select Properties.

   • Set Startup type to Automatic and click Start.

3. Repeat for QBCFMonitorService.

4. Restart the server and workstations.

Solution 6: Test Network Connectivity

Run a ping test from the workstation to the server to ensure they can communicate.

1. Press Windows + R, type cmd, and press Enter.

Type: cssCopyEditping [ServerName]

2.  Replace [ServerName] with your actual server’s name.

3. If packets are lost or connection fails, troubleshoot network hardware and DNS settings.

Solution 7: Map a Network Drive to the Company File

Sometimes direct IP mapping helps bypass name resolution errors.

1. Open File Explorer.

2. Click This PC > Map Network Drive.

3. Choose a drive letter and browse to your company file folder on the server.

4. Check Reconnect at sign-in and click Finish.

5. Open QuickBooks from this mapped drive path.

Solution 8: Add Server to Windows Hosts File

If DNS is unreliable, manually map the server name to its IP.

On the workstation, navigate to: makefileCopyEditC:\Windows\System32\drivers\etc

1. Open the hosts file in Notepad as Administrator.

Add a new line: cssCopyEdit[ServerIP]    [ServerName]

2. Save and restart QuickBooks.
