Understanding the QuickBooks Error H505
QuickBooks Error H505 typically indicates a failure in connecting to the company file due to firewall blocks, network disruptions, or misconfigurations in your multi-user settings.

It can be especially frustrating as it prevents multiple users from accessing the company file simultaneously, directly impacting your business productivity.
Common Causes of QuickBooks Error H505
The causes of this issue can vary, but the most common ones include:
- Incorrect or blocked firewall settings stopping QuickBooks from communicating across the network.
- The QuickBooks Database Server Manager not running or improperly configured on the host computer.
- Network issues or connectivity disruptions between client and server machines.
- Damaged or missing QuickBooks .ND files that manage network data.
- Incorrect entries in the Windows host file that block QuickBooks communication.
Identifying the root cause will help you apply the right fix quickly.
Steps to Fix QuickBooks Error H505
Here are proven troubleshooting steps you can follow to resolve QuickBooks error H505 in a methodical way:
1. Check Network Connectivity and Server Status
Ensure that the server hosting your QuickBooks company file is powered on and connected to the network. From client computers, ping the server to verify network connectivity. If the ping test fails, resolve the network issues first.
2. Verify QuickBooks Database Server Manager
On the host computer, open QuickBooks Database Server Manager and scan the folder containing the company file. This step allows the server to manage user connections properly. If the Database Server Manager is not installed, download and install it through the QuickBooks installation package.
3. Configure Firewall Settings
QuickBooks must have specific firewall ports open to communicate in multi-user mode. Open or unblock the following ports depending on your QuickBooks version (e.g., 8019, 56728-56730). Also, ensure that QuickBooks executable files (such as QBW32.EXE, QBDBMgrN.exe) are added to the exceptions/exclusions list of your firewall software.

4. Edit the Windows Host File
Incorrect host file entries can block QuickBooks communication and trigger error H505. To fix this, open the Windows host file on the server machine and add manual entries for your server IP address and the server name. This step resolves name resolution issues in the network.
5. Rename the QuickBooks .ND File
The .ND (Network Data) file helps QuickBooks find the company file over the network. If corrupted, it can cause connectivity problems. Rename the .ND file by adding “.old” at the end, then reopen QuickBooks and attempt multi-user access again.
