What is QuickBooks Error H202?

QuickBooks Error H202 belongs to the H-series of errors that occur when multi-user mode fails to establish a connection with the server. When this error appears, a message usually reads:

“This company file is on another computer, and QuickBooks needs some help connecting.”

Common Error Code:

H202 – Multi-user mode cannot connect to the server.



Why Does QuickBooks Error H202 Occur?

  • Incorrect hosting configuration

  • Firewall blocking communication

  • QuickBooks services not running

  • Corrupted .ND (Network Descriptor) file

  • Damaged DNS settings

  • Blocked ports required by QuickBooks

Each of these issues disrupts communication between the user’s workstation and the server where the company file is hosted.

  • You can’t open the company file in multi-user mode.

  • QuickBooks freezes or crashes during operation.

Relation to QuickBooks Error 30159

QuickBooks Error 30159 is related to payroll processing and is generally caused by a corrupted Windows file or misconfigured system setup.

How to Fix QuickBooks Error H202: Step-by-Step Guide

Solution 1: Run the QuickBooks Database Server Manager

  1. Download and install the QuickBooks Tool Hub from the official Intuit website.

  2. Open the Tool Hub and click on “Network Issues”.

  3. Select QuickBooks Database Server Manager.

  4. Click Start Scan and browse to the folder containing your company file.

  5. After scanning, the tool will fix firewall and permission issues automatically.

Pro Tip: Restart QuickBooks and try switching to multi-user mode again.



Solution 2: Ping the Server

If the server isn't reachable, QuickBooks can't operate in multi-user mode.

  1. On your workstation, press Windows + R, type cmd, and press Enter.

  2. Type ping [ServerName] (replace [ServerName] with your server’s actual name).

  3. If you receive slow or no response, you have a network connectivity issue.

In such cases, ensure all computers are on the same network and can communicate freely.



Solution 3: Verify QuickBooks Services

Ensure that QuickBooksDBXX and QBCFMonitorService are running.

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

  2. Look for QuickBooksDBXX (XX is the version year) and double-click it.

  3. Set the Startup Type to Automatic and click Start.

  4. Repeat for QBCFMonitorService.

Restart QuickBooks and check if the error persists.



Solution 4: Configure Windows Firewall Settings

QuickBooks requires specific ports to function in multi-user mode. If your firewall is blocking these ports, you’ll see H202 error.

Steps:

  1. Go to Control Panel > System and Security > Windows Firewall.

  2. Click Advanced Settings > Inbound Rules > New Rule.

  3. Choose Port, and click Next.

  4. Add these ports based on your version:

    • QuickBooks Desktop 2024: 8019, 56728, 55378-55382

    • QuickBooks Desktop 2023 and earlier versions use similar port ranges.

  5. Click Next, allow the connection, and name the rule “QB Inbound”.

Repeat the same for Outbound Rules.



Solution 5: Rename the .ND and .TLG Files

Corrupted or outdated network configuration files (.ND and .TLG) may cause connectivity problems.

  1. Navigate to your company file folder (e.g., C:\Users\Public\Documents\Intuit\QuickBooks\Company Files).

  2. Find files with the same name as your company file but with extensions .ND and .TLG.

  3. Rename them to .ND.old and .TLG.old.

QuickBooks will regenerate these files the next time you open the company file.



Solution 6: Create a New Folder for the Company File

  1. Create a new folder in a shared location on the server.

  2. Copy the .QBW file (your company file) into the new folder.

  3. Set appropriate Windows permissions to share this folder.

  4. Open the file from a workstation in multi-user mode.

This bypasses any path or permission issues with the old directory.



Solution 7: Add Server to Windows Hosts File

  1. On your workstation, go to: C:\Windows\System32\Drivers\Etc\hosts

  2. Open the hosts file with Notepad (Run as Administrator).

  3. Add the IP address and computer name of the server at the bottom.

Example: 192.168.1.12 QBServer

  1. Save the file and restart your computer.



Solution 8: Use QuickBooks File Doctor

QuickBooks File Doctor is another tool in the Tool Hub that fixes common network issues.

  1. Open the Tool Hub.

  2. Click on Company File Issues > Run QuickBooks File Doctor.

  3. Choose your company file and select Check your file and network.

  4. Let the scan complete and apply suggested fixes.



Solution 9: Check DNS Settings

Misconfigured DNS settings may also prevent your computer from finding the server.

  1. Press Windows + R, type ncpa.cpl, and press Enter.

  2. Right-click on your active network > Properties.

  3. Select Internet Protocol Version 4 (TCP/IPv4) > Properties.

  4. Ensure Obtain DNS server automatically is selected.

Alternatively, use Google DNS:

  • Preferred: 8.8.8.8

  • Alternate: 8.8.4.4
