What is QuickBooks Error H202?

QuickBooks Error H202 occurs when you're trying to open a company file located on another computer, and QuickBooks can't reach the server. This error typically appears with the following message:

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

It essentially means QuickBooks is unable to communicate with the host system due to misconfigured network settings or blocked ports.

Why QuickBooks Error H202 Happens (Main Causes)

Understanding the root causes helps prevent the issue from recurring. Here are the most common reasons:

1. Incorrect Hosting Configuration

If the hosting settings are not properly enabled on the server, QuickBooks cannot access the file.

2. Blocked Ports

QuickBooks requires specific ports to be open for multi-user mode. If they're closed or blocked by your firewall, you'll see Error H202.

3. Issues with QuickBooks Database Server Manager

If the QuickBooks Database Server Manager (QBDSM) isn’t running or installed properly on the host, access will be denied.

4. DNS Server Issues

Improper DNS settings can stop QuickBooks from recognizing the server location.

5. Damaged Network Data File (.ND)

The .ND file is essential for accessing files over a network. If it's corrupt or missing, QuickBooks can’t locate the file.

Signs You're Facing QuickBooks Error H202

Look for these red flags:

• QuickBooks freezes or lags when opening the company file.

• You can open the file locally but not over the network.

• The H202 error message pops up immediately upon launching.

• You can’t switch to multi-user mode.

Solutions to Fix QuickBooks Error H202

Now that you know the causes, let’s walk through the proven methods to resolve it.

 Solution 1: Use the QuickBooks File Doctor Tool

QuickBooks File Doctor can automatically identify and fix network issues.

Steps:

1. Download and install the QuickBooks Tool Hub.

2. Launch the Tool Hub and go to Company File Issues.

3. Click on Run QuickBooks File Doctor.

4. Select your company file and start the scan.

This tool will diagnose and fix issues with network connectivity.

 Solution 2: Verify Hosting Settings

Ensure that only the server is hosting the company file.

On the Workstations:

1. Open QuickBooks.

2. Go to File > Utilities.

3. If you see “Stop Hosting Multi-User Access”, select it.

4. Repeat this on all workstations.

On the Server (Host Computer):

• Make sure Hosting Multi-User Access is turned on.

 Solution 3: Check QuickBooks Services

Two services must be running:

• QuickBooksDBXX (XX = version number)

• QBCFMonitorService

Steps:

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

2. Locate the services above.

3. Right-click each and select Start or Restart.

4. Set them to Automatic in the Properties tab.

 Solution 4: Open QuickBooks Ports in Firewall

Open required ports to allow network traffic:

QuickBooks Version	Port Number
2024	8019, 56728, 55378-55382
2023	8019, 56727, 55373-55377
2022	8019, 56726, 55368-55372
2021	8019, 56725, 55363-55367

Steps:

1. Go to Control Panel > Windows Defender Firewall.

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

3. Select Port > TCP > Enter port numbers.

4. Allow the connection and name the rule (e.g., QB Ports).

5. Repeat for Outbound Rules.

 Solution 5: Add Server to Windows Hosts File

If DNS issues persist, manually map the server IP to the hostname.

Steps:

1. Open Notepad as Administrator.

2. Go to: C:\Windows\System32\drivers\etc\hosts

3. Add this line at the bottom:

   192.168.1.100   ServerName
   

4. Save and restart QuickBooks.

 Solution 6: Ping the Server

Test if the workstation can communicate with the server.

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

2. Type:

   nginx
   
   ping ServerName
   

3. If you receive a reply, the connection is fine. If not, there may be a network issue.

 Solution 7: Recreate the .ND File

Corrupted .ND files can cause H202. Recreating them can help.

Steps:

1. Go to the folder containing your company file.

2. Locate the .ND file (e.g., CompanyName.qbw.nd).

3. Right-click and delete it.

4. Open QuickBooks Database Server Manager.

5. Scan the folder containing your company file.

This will regenerate the .ND file and restore access.
