How to Fix QuickBooks Error H202 and H505

QuickBooks Desktop errors H202 and H505 can prevent users from opening a company file in multi-user mode. These errors usually occur when a workstation cannot establish a connection with the computer hosting the QuickBooks company file. Related network errors such as H101 and H303 can also appear when hosting settings or network communication are not configured correctly.

Fortunately, you can troubleshoot these errors by checking QuickBooks hosting settings, Database Server Manager, firewall permissions, Windows services, and network connectivity. Follow the solutions below to restore multi-user access.

What Causes QuickBooks Error H202 and H505?

QuickBooks Error H202 generally indicates that a workstation cannot communicate with the server where the company file is stored. H505 can occur when a workstation is incorrectly configured to host the company file instead of the designated server.

Common causes include:

• Incorrect QuickBooks hosting settings
• QuickBooks Database Server Manager not running
• Firewall restrictions
• Damaged or incorrect network configuration
• Problems with QuickBooks services
• Network connectivity issues between workstations and the server
• More than one computer configured for multi-user hosting

Before making changes, identify which computer stores your QuickBooks company file. This computer is your server, while the other computers connected to it are your workstations.

Fix QuickBooks H202 and H505 Using QuickBooks Tool Hub

The QuickBooks Tool Hub can help diagnose common QuickBooks Desktop problems. Install and run it on the server computer, and close QuickBooks before using the tool.

Step 1:Install QuickBooks Tool Hub

Download and install the latest available version of QuickBooks Tool Hub. Save the installation file in an easy-to-find location, such as your Windows desktop or Downloads folder.

Open QuickBooksToolHub.exe, follow the installation instructions, and accept the terms and conditions. After installation, double-click the Tool Hub icon to launch it. If you cannot find the icon, search for QuickBooks Tool Hub from the Windows Start menu.

Step 2: Run QuickBooks Database Server Manager

After opening Tool Hub:

1. Select Network Issues.
2. Choose QuickBooks Database Server Manager.
3. If QuickBooks is not installed on the server, follow the prompt to install it.
4. Select the company file folder and click Start Scan.
5. If the folder is not listed, browse to its location and start the scan.
6. Allow Database Server Manager to complete the scan.

The Database Server Manager can automatically repair relevant firewall permissions.

Once the scan finishes, open QuickBooks on the affected workstations and select File > Switch to Multi-user Mode. Remember to check the server too if it is also being used as a workstation.

Step 3: Run QuickBooks File Doctor

If H202 continues to appear, use QuickBooks File Doctor:

1. Open QuickBooks Tool Hub.
2. Select Company File Issues.
3. Click Run QuickBooks File Doctor.
4. Choose your company file from the list.
5. Select Check your Network.
6. Click Continue.
7. Enter your QuickBooks administrator password.
8. Select Next.

After the process completes, try switching the workstations to multi-user mode again. If they connect successfully, the H202 problem should be resolved.

Fix QuickBooks Error H202 Manually

If QuickBooks Tool Hub does not resolve the problem, use the following manual troubleshooting methods.

Solution 1: Check QuickBooks Services

First, verify that the required QuickBooks services are running on your server.

If you use the full QuickBooks Desktop program on the server, check the hosting setting first. Open QuickBooks and select File > Utilities. If you see Host Multi-User Access, select it. If you see Stop Hosting Multi-User Access, leave it unchanged.

Next, check QuickBooksDBXX and QBCFMonitorService:

1. Open the Windows Start menu.
2. Search for Run and open it.
3. Enter services.msc.
4. Press Enter.
5. Find QuickBooksDBXX.
6. Open its properties.
7. Set Startup type to Automatic.
8. Make sure the service status shows Running or Started.
9. Open the Recovery tab.
10. Set the first, second, and subsequent failures to Restart the Service.
11. Click Apply and OK.

Repeat the same process for QBCFMonitorService.

Afterward, open QuickBooks on the workstations and try File > Switch to Multi-user Mode.

Solution 2: Add QuickBooks Services to the Windows Admin Group

QuickBooksDBXX and QBCFMonitorService may need appropriate administrator permissions on the server. Give both services the required Windows administrator access and then test QuickBooks again from the server and workstations.

Solution 3: Configure the Windows Firewall

A firewall can prevent QuickBooks from communicating properly across the network. Make sure the server allows QuickBooks through the Windows firewall and configure the required QuickBooks firewall exceptions.

Once the firewall settings are updated, open QuickBooks on the affected workstations and select File > Switch to Multi-user Mode.

Solution 4: Test the Network Connection

If H202 continues, test the connection between the workstation and the server.

First, turn on Network Discovery and File and printer sharing on the server and affected workstations. Go to the Windows network settings and make sure network discovery is enabled.

Next, identify the server name:

1. Open Run on the server.
2. Enter CMD.
3. Press Enter.
4. Type ipconfig/all.
5. Press Enter.
6. Find Host Name under Windows IP Configuration.
7. Record the server name.

On the affected workstation, open Command Prompt and enter:

ping your-server-name

Replace your-server-name with the actual server name.

Repeat the test on every workstation experiencing H202. If you receive replies for every packet without packet loss, the server connection is working properly. If you experience packet loss or very slow responses, the network may require assistance from an IT professional.

How to Fix QuickBooks Error H505, H101, and H303

H505, H101, and H303 can occur when one or more workstations are incorrectly configured to act as the QuickBooks server. Only the computer that actually hosts the company files should have multi-user hosting enabled.

To check the workstations:

1. Open QuickBooks on a workstation showing the error.
2. Do not open the company file.
3. Select File > Utilities.
4. If Host Multi-User Access appears, do not select it.
5. If Stop Hosting Multi-User Access appears, select it.
6. Repeat the process on the other affected workstations.

Then check the actual server:

1. Open QuickBooks on the server.
2. Go to File > Utilities.
3. Select Host Multi-User Access if it is available.
4. Do not select Stop Hosting Multi-User Access.

This ensures that the server is the only computer configured to host the QuickBooks company file.

Final Thoughts

QuickBooks Error H202 and H505 are commonly associated with multi-user network communication and hosting configuration. Start with QuickBooks Tool Hub and Database Server Manager, then check QuickBooks services, firewall permissions, network connectivity, and hosting settings.

If H202 continues after these troubleshooting steps, investigate the network connection between the server and workstations. For H505, H101, or H303, pay particular attention to which computers have multi-user hosting enabled. Correctly identifying the server and keeping hosting settings configured properly can help restore access to the company file.
