How to Fix QuickBooks Error Code H505 (Multi-User Mode Access Issue)

Most of the time, users encounter problems while accessing or creating a company file in QuickBooks. The company file helps them manage their finances, generate reports, and file taxes. If the company file detects any error, it can lead to data loss, incorrect financial statements, and other issues that can affect the company’s financial health.

One such error is QuickBooks Error H505, which indicates trouble accessing company files that are stored on another device. It usually happens due to improper hosting settings, incorrect DNS settings, or interference of malware with QuickBooks.

In this comprehensive guide, you will learn WHAT QuickBooks Error H505 is, WHY it occurs, and HOW it can be resolved.

What is QuickBooks Error h505 & How does it Look when it occurs?

QuickBooks error H505 indicates that something is blocking the multi-user connection to your server. The error code H505 refers to the issue faced by a user when his system is unable to connect with the other computer in the network that is hosting the company file. This error belongs to the H series QB error, which is commonly known for network issues that occur when a user tries to access the company file stored on the server.

The error code reads: This company file is on another computer, and QuickBooks needs some help connecting.

It must be noted that in a multi-user mode, a company file should be hosted on a single workstation, which should be the server. Though, in a network, the user may access company files on another computer, if the above condition is not fulfilled, it will cause this particular error.

What are the causing roots behind the QuickBooks Error h505

The error H505 in QuickBooks brings some technical glitches in the network setup that interrupt the connection between different workstations on the server.

Although every problem comes with a solution, before getting into the solutions, it is important to learn the actual causes that led to the QuickBooks Error H505.

• When the background apps are being used at the same time when QuickBooks is used.
• When Windows firewall or other third-party security services interfere with the communication between computers in the network,
• When the hosting configurations are improper or incorrect.
• When the Network Data File (.ND), which QuickBooks uses to build a connection between all the computers on the network, is damaged or corrupted,
• When the QuickBooksDBXX service is not activated.
• When QBDataServiceuserXX may not have proper Read/Write permissions.
• When the QuickBooks Database Server fails to scan the QuickBooks File Folder.
• When QuickBooks cannot retrieve the IP address of the system or server hosting the company file.

How can we identify the effect of QuickBooks Error h505

This particular issue, the error H505, can be noticed on the system when a user is not able to use the multi-user mode in QuickBooks. This symptom is noticed because the company file is stored on a network, and due to this error, the user is unable to connect with the other computer in the network that is hosting the company file.

Also, you may notice that your Windows keeps crashing again and again because your system stops responding to QuickBooks. Generally, Windows becomes unresponsive when any components that are important for the functioning of QuickBooks need to be included. If the user is unable to access a company file, it is possible that the company file’s components, such as .ND files, .tlg files, etc., are missing.

You may notice that Windows freezes periodically. This happens due to the mismatch of updates. For instance, your QuickBooks version is not compatible with Windows. In this case, you have to update them accordingly.

Solution Part 2

If the solutions mentioned above do not resolve the error H505 in QuickBooks, then follow the steps mentioned below:

1.    End The Running Background Process & Login As System Administrator

There could be multiple background programs that may have been initiated for the user, and then the user may not need them after completing certain tasks. The QuickBooks background programs that are still open may interfere with the current tasks. Another reason for this is when another user is doing some task on QuickBooks software, which is limited to one user at a time, even in a multi-user mode.

You have to use Windows Task Manager to close QuickBooks background programs that are not in use. Follow the instructions to open the task manager:

• The first method is:

• Another method is to use keyboard shortcuts:

3. Follow the hidden files and folders.

In case you are not able to find the Windows folder in This PC:

1. To view hidden files, click on the View tab and then select Hidden Items.
2. This will allow you to see the hidden files.
3. Next, right-click on the host’s File, select Open with, and then choose Notepad.

1. Make sure that Windows gets Entry Permissions to the company files.
2. Now, copy the .qbw file into the new folder.
3. Go to Multi-user mode.
4. Now open the company file to complete this procedure.

5.    Check the services on the server

QuickBooks Database Server Manager creates a Network Data File (.ND file), which is stored on the host workstation. Network Data (.ND) files are configuration files that allow QuickBooks Desktop to access a company file in a network or multi-user mode. An .ND file is created in the same folder as the company file and is identified with an .ND file extension, such as MyCompanyFile.nd or MyCompanyFile.qbw.nd.

The QuickBooks Database Server Manager (QBServerUtilityMgr.exe) creates .ND files that identify the database server the Program will use. QuickBooks Database Server Manager can be used with QuickBooks Tool Hub. You have to download QuickBooks Tool Hub and run QuickBooks Database Server Manager.

Also, With the latest update, some additional file components get downloaded in QuickBooks, which can help access the company file easily. It also ensures an automatic diagnostic procedure, which helps in the automatic detection and resolution of any error.
