QuickBooks is a powerful accounting tool used by millions of businesses worldwide. However, like any complex software, it can sometimes encounter errors that disrupt workflow. Among the most common issues faced in multi-user mode are QuickBooks Error H202 and H505. These errors typically occur when a user attempts to switch to multi-user mode but cannot connect to the company file hosted on another computer.
If you encounter this issue, do not worry. You can call +1-866-500-0076 for expert guidance, or follow the steps outlined in this comprehensive guide to troubleshoot and resolve the error yourself.
Understanding QuickBooks Error H202 / H505
QuickBooks Error H202 and H505 indicate a connection problem between the workstation and the server hosting the company file. When QuickBooks attempts to communicate with the server in multi-user mode, it requires certain configurations to be in place:
- Correct hosting settings
- Proper firewall configurations
- Functional DNS settings
When any of these configurations fail, QuickBooks cannot access the company file remotely, triggering the H202 or H505 error.
Symptoms of the Error:
- Inability to switch to multi-user mode
- A warning message stating: “This company file is on another computer, and QuickBooks needs some help connecting.”
- The workstation shows an H202 or H505 error code
Why Does Error H202 / H505 Occur?
Understanding the root cause is essential before fixing the error. Common reasons include:
-
Incorrect Hosting Settings:
If multiple computers are hosting the company file or hosting is not set correctly, QuickBooks cannot identify the server. -
Firewall or Security Software Restrictions:
Firewalls can block communication between the server and the workstation. -
Incorrect DNS or IP Settings:
QuickBooks relies on proper DNS settings to locate the server. Misconfigured DNS or IP addresses may cause H202/H505 errors. -
Damaged or Missing Network Files:
The .ND (Network Data) file and .TLG (Transaction Log) file are essential for multi-user access. If corrupted, connection errors occur.
Step-by-Step Solutions to Fix QuickBooks Error H202 / H505
Below are effective methods to resolve these errors. You can perform these steps yourself or call +1-866-500-0076 for instant support.
1. Verify Hosting Settings
- On the server computer, open QuickBooks.
- Go to File > Utilities.
- Ensure that Host Multi-User Access is enabled only on the server.
- On workstations, make sure Stop Hosting Multi-User Access is selected.
2. Use QuickBooks Database Server Manager
QuickBooks Database Server Manager ensures that company files are accessible on the network.
- Install or update QuickBooks Database Server Manager on the server.
- Open the tool and scan the folder containing your company files.
- Restart all workstations and attempt to switch to multi-user mode.
3. Configure Firewall Ports
QuickBooks requires specific firewall ports to allow communication:
- Open your firewall settings.
- Ensure QuickBooks ports (e.g., 8019, 56728–56731 for QuickBooks 2025) are open.
- Allow qbupdate.exe, qbserverutility.exe, and qbdbmgr.exe through the firewall.
4. Edit the Hosts File
The hosts file maps IP addresses to server names, helping QuickBooks locate the company file.
- Navigate to
C:\Windows\System32\drivers\etc\hosts. - Add the IP address of the server followed by the server name.
- Save the file and restart all QuickBooks applications.
5. Rename the .ND File
The .ND file stores network configuration. Renaming it forces QuickBooks to create a new one.
- Locate the .ND file in the company file folder.
- Rename it to
CompanyFileName.nd.old. - Open QuickBooks and attempt multi-user mode.
6. Check DNS and IP Settings
- Ensure that all workstations can ping the server IP.
- If using DHCP, assign a static IP to the server computer to prevent IP changes.
