What Is QuickBooks Error H202?

QuickBooks Error H202 belongs to the H-series errors that typically occur when a user tries to access a company file located on another computer (server), and QuickBooks cannot reach the server due to network issues or configuration problems.

This error usually pops up with a message that reads:

"You are trying to work with a company file located on another computer, and this copy of QuickBooks cannot reach the server (H202)."

In essence, the error prevents users from accessing the QuickBooks file in multi-user mode — a critical feature for many businesses.

Common Symptoms of QuickBooks Error H202

Recognizing the signs of this error can help you identify and resolve the issue faster. Here are some typical symptoms:

• QuickBooks freezes or becomes sluggish in multi-user mode.
  
  

• You see “Error Code H202” when trying to open a company file.
  
  

• You’re unable to access the company file stored on another computer.
  
  

• QuickBooks fails to connect to the server.
  
  

• An error message indicates QuickBooks is trying to communicate with the company file but cannot reach the server.
  
  

What Causes QuickBooks Error H202?

To effectively resolve QuickBooks Error H202, it's essential to understand its root causes. Here are the most common triggers:

1. Incorrect Hosting Configuration

When the QuickBooks hosting settings are not configured properly, the workstations can’t connect to the server that stores the company file.

2. Blocked Ports

QuickBooks uses specific ports to communicate over the network. If these ports are blocked by a firewall or antivirus, the connection fails.

3. DNS Server Issues

Incorrect DNS settings or a misconfigured network can prevent QuickBooks from locating the server computer.

4. QuickBooks Database Server Manager Not Running

This service is essential for multi-user mode. If it’s not running on the server, access from other computers will be blocked.

5. Damaged .ND File

The Network Descriptor (.ND) file helps QuickBooks connect to company files on the network. If it’s corrupted, it can lead to H202 errors.

6. Incorrect File Path

If the path to the company file is wrong or inaccessible, QuickBooks will not be able to connect.

How to Fix QuickBooks Error H202 (Step-by-Step)

Now that you know what causes the issue, let’s walk through the most effective methods to fix QuickBooks Error H202 fast:

Fix 1: Use the QuickBooks Database Server Manager

1. Download and install the QuickBooks Tool Hub (if not already installed).
   
   

2. Launch the Tool Hub and go to Network Issues.
   
   

3. Click on QuickBooks Database Server Manager.
   
   

4. Use it to scan the folder where your company file is stored.
   
   

5. Once the scan completes, try opening your company file in multi-user mode again.
   
   

If you still see the error, continue to the next fix.

Fix 2: Check Hosting Settings on All Computers

1. Open QuickBooks on each workstation.
   
   

2. Go to File > Utilities.
   
   

3. If you see the option “Host Multi-User Access”, leave it as is.
   
   

4. If you see “Stop Hosting Multi-User Access”, click it.
   
   

5. Repeat this on every workstation to ensure only the server is hosting the file.
   
   

Fix 3: Ping the Server from Workstations

This helps verify if the workstation can reach the server.

1. On the workstation, press Windows + R, type CMD, and hit Enter.
   
   

2. Type ping [server name] and press Enter.
   
   

If packets are lost or there’s no response, there’s a network issue that must be resolved.

Fix 4: Configure Firewall and Add QuickBooks Ports

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

3. Right-click and select Rename. Add .old at the end (e.g., companyfile.qbw.nd.old).
   
   

4. Open QuickBooks again. It will create a new .ND file automatically.
   
   

Fix 6: Add Server to Windows Hosts File

1. On the workstation, open C:\Windows\System32\Drivers\Etc\hosts using Notepad as Administrator.
