# How to Fix QuickBooks Error H202 – (Problem with Multi-user Hosting Setup)?
QuickBooks Desktop is widely used by businesses that rely on multi-user access to collaborate effectively. However, one of the most frustrating issues that arises in multi-user mode is QuickBooks Error H202. This error prevents workstations from connecting to the company file stored on the server computer. When QuickBooks Desktop cannot communicate with the server hosting the company file, it shows:
“Error H202: This company file is on another computer, and QuickBooks needs some help connecting.”
If you’re experiencing QuickBooks Error H202 and need a reliable solution, this comprehensive guide will walk you through everything—from understanding the causes to step-by-step troubleshooting. If you prefer expert help instead, you can immediately call QuickBooks-certified support at 1-888-394-9046 or 1-866-596-1988 for faster resolution.
What Is QuickBooks Error H202?
QuickBooks Error H202 appears whenever a workstation fails to reach the company file located on the server computer. This error belongs to the “H-Series,” which includes H101, H202, H303, and H505—errors directly connected to hosting misconfiguration or multi-user communication issues.
In simple terms, Error H202 means the workstation cannot access the company file because:
The server is not correctly hosting the file.
QuickBooks Database Server Manager is not running.
A firewall is blocking communication.
DNS settings are incorrect.
Network issues exist between the workstation and server.
In many cases, calling an expert at 1-888-394-9046 or 1-866-596-1988 helps users get back up and running without downtime.
Why Does QuickBooks Error H202 Occur?
Before diving into solutions, it’s important to know why this error happens. Some common causes of QuickBooks Error H202 include:
1. QuickBooks Cannot Reach the Server
The workstation may be unable to recognize or connect with the server computer hosting the company file.
2. Hosting Settings Are Incorrect
Only the server should have hosting enabled, not the workstation. Incorrect hosting configuration triggers H202.
3. A Firewall Is Blocking QuickBooks Ports
QuickBooks uses specific ports to communicate in multi-user mode. If these ports are blocked, the workstation cannot connect.
4. QuickBooks Database Server Manager Issues
If QuickBooks services like QBCFMonitorService or QuickBooksDBXX are not running, multi-user communication fails.
5. Wrong DNS or Network Configuration
Incorrect network settings or damaged DNS structures can interrupt communication between systems.
6. Damaged or Corrupted .ND File
Network Descriptor (.ND) files help QuickBooks identify the exact location of the company file. If damaged, the workstation loses access.
Regardless of the cause, all types of Error H202 can be resolved through systematic troubleshooting—or with assistance from QuickBooks experts at 1-888-394-9046 or 1-866-596-1988.
Signs and Symptoms of QuickBooks Error H202
You’ll notice QuickBooks Error H202 if:
QuickBooks freezes when switching to multi-user mode.
You receive the pop-up “QuickBooks Error H202.”
Workstations cannot open the company file stored on the server.
QuickBooks runs slower in network mode.
Communication between server and workstations is interrupted.
If you experience repeated interruptions, contact support at 1-888-394-9046 or 1-866-596-1988 for help.
How to Fix QuickBooks Error H202 – Complete Step-by-Step Guide
Below are the most effective methods to resolve Error H202. Follow them in order for the best results.
Solution 1: Verify Correct Hosting Configuration
Incorrect hosting configuration is the most common cause of H202.
Step 1 – On Every Workstation
Open QuickBooks Desktop.
Pay attention to the top bar: it should say “WORKSTATION”.
Go to File > Utilities.
If you see “Host Multi-User Access”, DO NOT click it.
If you see “Stop Hosting Multi-User Access”, select it to disable hosting.
Step 2 – On the Server
Open QuickBooks on the server.
Go to File > Utilities.
Ensure “Host Multi-User Access” is selected.
If not, activate hosting on the server.
After correcting hosting settings, try switching to multi-user mode again.
If hosting still fails, an expert technician at 1-888-394-9046 or 1-866-596-1988 can help configure it quickly.
Solution 2: Use QuickBooks Database Server Manager (QBDSM)
QuickBooks Database Server Manager is essential for managing multi-user access.
Step-by-Step Instructions:
Open QuickBooks Tool Hub (download if needed).
Go to Network Issues.
Select QuickBooks Database Server Manager.
Choose Scan Folders.
Browse to the folder containing your company (.QBW) file.
Click Scan.
After scanning, QBDSM automatically repairs network-related issues.
If the tool identifies missing permissions or network issues you can’t fix, call 1-888-394-9046 or 1-866-596-1988 for help.
Solution 3: Restart QuickBooks Services
Two services must be running on the server:
QuickBooksDBXX (XX = version year)
QBCFMonitorService
Steps:
Press Windows + R.
Type services.msc and press Enter.
Locate QuickBooksDBXX.
Right-click → Restart.
Set Startup Type to Automatic.
Repeat for QBCFMonitorService.
Once restarted, attempt opening the file in multi-user mode.
Solution 4: Configure Firewall Settings for QuickBooks
Your firewall may be blocking QuickBooks communication channels.
Step-By-Step:
Open Windows Firewall.
Go to Advanced Settings.
Select Inbound Rules > New Rule.
Choose Port → Click Next.
Enter QuickBooks version-specific ports (for example: 8019, 56728, 55378).
Click Allow the Connection.
Repeat for Outbound Rules.
Firewall misconfiguration is a common root cause in businesses—calling 1-888-394-9046 or 1-866-596-1988 can help speed up resolving your settings.
Solution 5: Fix or Recreate the Damaged .ND File
A corrupted .ND (Network Descriptor) file can trigger Error H202.
Steps to Fix the .ND File:
Navigate to the QuickBooks company file folder.
Locate the file [yourcompanyfilename].ND.
Right-click → Rename → add .old at the end.
Open QuickBooks Database Server Manager.
Rescan the folder.
This will create a fresh .ND file and re-establish server communication.
Solution 6: Test Network Connectivity
Use the Ping command to test communication between workstation and server.
Steps:
On the workstation, open Command Prompt.
Type:
ping [server name]
Press Enter.
If ping returns packet loss or timing issues, your network may be unstable.
For network diagnostics, call 1-888-394-9046 or 1-866-596-1988.
Solution 7: Add Server to Windows Host File
Editing the Hosts file can correct DNS issues.
Steps:
Navigate to:
C:\Windows\System32\drivers\etc
Open hosts file in Notepad (Run as Administrator).
Add your server IP address and server name at the end of the file.
Save the file.
Restart QuickBooks.
Solution 8: Create a New Folder for the Company File
Sometimes folder permissions cause H202.
Steps:
On the server, create a new folder.
Copy the company file (.QBW) into the new folder.
Ensure folder has full permissions:
Read
Write
Modify
Share the folder on the network.
Then try accessing the file again.
Solution 9: Disable Antivirus Temporarily (If Applicable)
Some third-party antivirus software blocks QuickBooks connections.
Temporarily disable your antivirus, then try opening the file.
If this fixes the issue, create QuickBooks exceptions in the antivirus settings.
If unsure how to configure antivirus settings, call 1-888-394-9046 or 1-866-596-1988.
Solution 10: Use QuickBooks Tool Hub Repair Features

Use These Tools:

Each feature helps eliminate causes linked to Error H202.
