For quick help, you can always call +1(866)500-0076 to reach a QuickBooks expert for assistance.


Understanding QuickBooks Error H202

QuickBooks Error Code H202 appears when QuickBooks Desktop cannot connect to the company file located on another system (the server). This typically happens when you try to switch from single-user to multi-user mode.


The full error message usually reads:


“Error code H202: This company file is on another computer, and QuickBooks needs some help connecting.”


In simple terms, the H202 QuickBooks Error means that the software cannot establish a communication link with the database server that hosts your company file


Why Does QuickBooks Error H202 Occur?

The QuickBooks H202 Error is caused by connectivity issues between your workstation and the server that stores your company file. Several factors could be behind this communication breakdown:

  1. Blocked Ports: QuickBooks uses specific database ports to communicate between computers. If these ports are blocked by your firewall or security software, the connection fails.

  2. Incorrect Hosting Configuration: If hosting settings are misconfigured on the server or workstations, it can trigger H202 Error QuickBooks.

  3. QuickBooks Database Server Manager Not Running: The QuickBooks Database Server Manager (QBDBMgrN) helps manage multi-user connections. If it’s not running, the workstations cannot access the company file.

  4. Damaged or Corrupted .ND File: The Network Data (.ND) file helps QuickBooks locate the company file over a network. A corrupted or damaged .ND file can cause connection issues.

  5. DNS or IP Address Issues: Incorrect DNS configuration or network name resolution problems may also lead to the QuickBooks Error H202.

  6. Server Not Reachable: If the server computer is turned off, disconnected, or unreachable, users will experience this error while trying to access the file in multi-user mode.


Symptoms of H202 QuickBooks Error

You can recognize the QuickBooks Error Code H202 through several telltale signs, including:

  • Inability to switch to multi-user mode.

  • The error message “QuickBooks Error H202” appears on your screen.

  • The company file opens in single-user mode but not multi-user mode.

  • QuickBooks performance slows down when accessing files.

  • QuickBooks freezes or crashes frequently.

  • You experience delays while accessing files over a network.


How to Fix QuickBooks Error H202 – Step-by-Step Solutions

There are several methods to fix H202 QuickBooks Error depending on the underlying cause. Follow these expert-tested solutions carefully.



Solution 1: Verify QuickBooks Hosting Settings

Incorrect hosting setup is one of the main reasons for QuickBooks Error Code H202.

  1. Open QuickBooks on each workstation.

  2. Go to File → Utilities.

  3. If you see Host Multi-User Access, do not click on it. That computer should not host the file.

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


Tip: Only the server computer should host the company file. Workstations should not.

After adjusting the hosting settings, restart QuickBooks and check if the error persists.


Solution 2: Run QuickBooks Database Server Manager

The Database Server Manager helps QuickBooks communicate between systems.

  1. On the server computer, open the QuickBooks Database Server Manager.

  2. Click Start Scan if your company file folder is listed. Otherwise, click Browse, locate the folder, and then Start Scan.

  3. After the scan, click Close.

  4. Restart the QuickBooksDBXX service (where XX represents your QuickBooks version).


Once completed, open QuickBooks in multi-user mode to test the connection.


Solution 3: Ping the Server

Network connectivity issues can also trigger QuickBooks Error H202. To verify your connection:

  1. On the workstation, open the Command Prompt (CMD).

  2. Type ping [ServerName] and press Enter.

    • Example: ping Server01

  3. If you receive slow replies or packet loss, you may have a network issue.


In that case, contact your network administrator or call +1(866)500-0076 for expert help to resolve network connectivity problems.


Solution 4: Add QuickBooks Ports to Your Firewall

Sometimes, your firewall blocks the ports required for multi-user mode.

Here’s how to manually configure your firewall:

  1. Open Control Panel → Windows Defender Firewall → Advanced Settings.

  2. Click Inbound Rules → New Rule.

  3. Choose Port → Next.

  4. Select TCP and enter the following ports for your version of QuickBooks:

    • QuickBooks 2024: 8019, 56740–56745

    • QuickBooks 2023: 8019, 56736–56740

  5. Click Next → Allow the Connection → Finish.

Repeat the same for Outbound Rules.


After configuring, restart QuickBooks and try opening the company file again.


Solution 5: Delete and Recreate the .ND File

The .ND (Network Data) file helps QuickBooks identify the company file over a network. A corrupted file can cause QuickBooks Error H202.

To recreate it:

  1. Go to the folder where your company file is stored.

  2. Locate the file with the same name as your company file but ending in .ND (e.g., CompanyFileName.qbw.nd).

  3. Right-click and choose Delete.

  4. Open QuickBooks Database Server Manager → click Start Scan to recreate the file.


Once done, reopen QuickBooks in multi-user mode.


Solution 6: Use the QuickBooks Tool Hub

Intuit provides an official repair utility called QuickBooks Tool Hub, which can fix network and company file issues automatically.

  1. Download the latest QuickBooks Tool Hub from Intuit’s official website.

  2. Install and open the tool.

  3. Go to the Network Issues tab.

  4. Select QuickBooks Database Server Manager and follow the on-screen prompts.

This automated tool can resolve QuickBooks H202 Error without manual configuration.


Solution 7: Check the QuickBooks Services

Ensure that essential QuickBooks services are running:

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

  2. Locate the following services:

    • QuickBooksDBXX

    • QBCFMonitorService

  3. Ensure both are Running and set to Automatic.

If not, right-click each → select Properties → set Startup Type to Automatic → click Start → then OK.


Restart QuickBooks to confirm the issue is fixed.


Solution 8: Configure Your DNS Settings

Incorrect DNS settings can block the connection to the server and trigger the H202 QuickBooks Error.

  1. On the workstation, open Control Panel → Network and Sharing Center → Change Adapter Settings.

  2. Right-click your active network → select Properties.

  3. Choose Internet Protocol Version 4 (TCP/IPv4) → click Properties.

  4. Select Use the following DNS server addresses and enter:

    • Preferred DNS: 8.8.8.8

    • Alternate DNS: 8.8.4.4


Restart your computer and test QuickBooks again.


Preventing QuickBooks Error Code H202 in the Future

Once you’ve fixed the issue, take preventive measures to avoid the QuickBooks Error H202 from recurring:

  • Always ensure that your server and workstations are connected to a stable network.

  • Regularly update your QuickBooks Desktop and Database Server Manager.

  • Exclude QuickBooks files and folders from antivirus scans.

  • Keep your Windows firewall exceptions updated.

  • Do not host the company file on multiple workstations simultaneously.

  • Run QuickBooks File Doctor periodically to check network configurations.


By maintaining these practices, you can minimize downtime and keep your QuickBooks running smoothly.
