QuickBooks has become one of the most reliable accounting tools for small and medium-sized businesses. However, even this robust software can face technical glitches that interrupt workflow. One of the most common issues is QuickBooks Error H202, which usually arises when trying to access a company file in multi-user mode.

What is QuickBooks Error H202?

QuickBooks Error H202 occurs when a workstation (a computer other than the one hosting the company file) fails to connect to the server hosting the data. This prevents multi-user mode from functioning properly. Essentially, your system is unable to establish a stable connection with the QuickBooks Database Server Manager.

Common Causes of QuickBooks Error H202

Before resolving the error, it is helpful to understand why it appears. Some typical causes include:

  1. Incorrect hosting configuration on workstations.

  2. Blocked communication due to Windows Firewall settings.

  3. Issues with the QuickBooks Database Server Manager not running properly.

  4. DNS server conflicts that prevent data exchange.

  5. Damaged or incorrect .ND file associated with the company file.

  6. Hosting misconfiguration when multiple systems attempt to host the file simultaneously.

Signs That You Are Facing QuickBooks Error H202

  • Error message displaying “Error H202” on your screen.

  • QuickBooks crashes or gets stuck in multi-user mode.

  • Company files not accessible on other systems.

  • Unstable performance while switching to multi-user mode.

Step-by-Step Solutions to Fix QuickBooks Error H202 (2025)

Follow these proven methods to resolve the problem:

1. Verify Hosting Settings

  1. Open QuickBooks on each workstation.

  2. Go to File > Utilities.

  3. If you see “Host Multi-User Access”, do NOT click it. This means hosting is disabled already on that workstation.

  4. Only the server should have hosting enabled.

2. Run QuickBooks Database Server Manager

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

  2. Re-scan the folder where your company file is stored.

  3. If the file appears in the list, try opening it again in multi-user mode.

3. Configure Windows Firewall

  1. Open Control Panel > Firewall Settings.

  2. Add QuickBooks programs (QBDBMgrN.exe and QBW32.exe) as allowed applications.

  3. Ensure TCP ports 8019, 56728, 55378-55382 are open.

  4. Restart QuickBooks and switch to multi-user mode.

4. Rename the .ND File

  1. Locate the folder where your company file is stored.

  2. Find the .ND file (example: CompanyFileName.qbw.ND).

  3. Right-click and rename it (e.g., CompanyFileName.qbw.ND.old).

  4. Restart QuickBooks so it can create a fresh .ND file automatically.

5. Use the QuickBooks Tool Hub

  1. Download and install the QuickBooks Tool Hub (latest version for 2025).

  2. Open the Tool Hub and select Network Issues.

  3. Choose QuickBooks Database Server Manager and follow the prompts.

6. Check Network Connectivity

  1. Open the Run command and type ping [server name].

  2. If packets are lost, check network settings and connections.

  3. Ensure reliable connectivity between workstations and the server.

7. Adjust DNS Settings

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

  2. Right-click your network and go to Properties.

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

  4. Enter a preferred DNS server such as 8.8.8.8 (Google DNS).

Preventing QuickBooks Error H202 in the Future

While fixing the error restores normal functioning, prevention is equally important:

  • Keep QuickBooks and Windows updated regularly.

  • Configure firewall and antivirus properly.

  • Keep QuickBooks Database Server Manager running at all times.

  • Ensure only the server has hosting enabled—never on workstations.

  • Use stable internet and networking equipment.
