Method 3- Resolve Database Server Manager Issues

The QuickBooks Database Server Manager is responsible for the multi-user network setup and smooth data flow over it. You’ll straightaway run into issues while hosting the data file if DBSM doesn’t run in the background while switching the server to multi-user mode for hosting the data file. You’ll have to get rid of the DBSM issues to ensure QuickBooks Desktop error 6120 0 doesn’t come up again. Use these steps-

Step 1- Rename the Damaged .TLG & .ND Files

Transaction Log (.tlg) file holds the recent transactions as your company file, and the Network Descriptor (.nd) contains the file paths to the data source and the workstations. These files are essentially required for multi-user network setup, as DBSM won’t start if the files are damaged. An easy way to go through the issue is by renaming both the files, as shown below-

• Press Windows + E and visit C: Users\Public\PublicDocuments\Intuit\QuickBooks20XX on the File Explorer.
• Right-click the .tlg and .nd files (individually) you see inside the QB folder and select Rename.
• Type ‘.OLD’ as an extension at the end of the file names and save both files.
• Launch your QB Database Server Manager and move under the Scan Folders tab.
• Tap Browse and enter the location of the folder where you renamed the .tlg and .nd files.
• Tap Start Scan and wait until the DBSM scans all the QB folder contents.

Step 2- Restart DBSM Processes

QuickBooks can also struggle to set up a network if security programs or other applications on your system do not allow the DBSM processes to run in the background. DBSM can also malfunction due to minor glitches stopping its background processes. Restart DBSM processes using these steps to fix the issue-

• Open the Task Manager (Windows + Shift + Esc) on your PC and go to the Processes tab.
• Search for all the QB-related processes like QBDBMgrN.exe, QBDBMgr.exe, QBW32.exe, etc.

• Right-click all the QB processes individually and click End Task to stop them all.
• Reboot your system and try setting up a multi-user network on your QB again.

Method 4- Ensure the QB Hosting Settings are Correct

A significant cause for the occurrence of QuickBooks Error code 6120, 0 is workstations running in multi-user mode to host the company file. Only the server computer is allowed to run in multi-user mode for sharing the company files, and even a single workstation running in multi-user mode can trigger the company file error on your system. Arrange the QB hosting settings correctly using the following steps-

• Launch QB Desktop on the workstation that displays this error code and access the File menu.
• Select Utilities in the drop-down menu and click Stop hosting multi-user access.

• Turn all the workstations to single-user mode using the above steps and approach the server.
• Go to QB’s File menu and select Utilities.
• Tap Host multi-user access to switch the server to multi-user mode.

• Reboot all the systems and open the company file on the server in multi-user mode.

If QuickBooks runs into the company file error again, jump to the next solution.

Method 5- Ensure QB is Allowed to Bypass the Windows Firewall

A primary reason for QuickBooks error 6120 stopping you from accessing the company file can be restrictions imposed by the Windows Firewall on your PC. QuickBooks won’t be able to access the system drives or exchange data using the multi-user network if the firewall port (8019) is blocked. In this condition, you must add firewall exceptions for QuickBooks to ensure its functions aren’t restricted. Here’s how-

Step 1- Creating Firewall Ports for QB Desktop

In case you have multiple QB versions installed on your system, apply the following steps to add firewall ports for each of them-

• Go to the Control Panel using the Settings (gear icon) option in the Windows Start menu.
• Open the Windows Defender Firewall settings window and select the Advanced Settings option.
• Right-click Inbound Rules and select the New Rule option.
• Tap Port, click Next, and choose TCP in the following window.
• Single-click the text column adjacent to Specific Local Ports and use the following list to fill in the firewall ports according to your QB product-
  • QuickBooks 2017: 8019, 56727, 55373-55377.
  • QuickBooks 2018: 8019, 56728, 55378-55382.
  • QuickBooks 2019: 8019, XXXXX.
  • QuickBooks 2020 and above: 8019, XXXX.

Tip: QuickBooks Desktop 2019 or newer versions use Dynamic Ports, assigned when you install the software on your computer. You can easily find the port number in the Database Server Manager using these steps-

• Run the QuickBooks DBSM and go to the Port Monitor tab.
• Specify your QB version to find the Port Number you’ll use as a Firewall exception.

Although the Dynamic Port number is automatically allocated during installation, you can use the Renew option to change it. If you choose to change the port number, click Start Scan in the Scan Folders tab afterwards to reset the firewall permissions.

• Enter the port numbers precisely and click Next.
• Select Allow the connection option and tap Next again.
• Make sure to select all the profiles mentioned in the software prompt and provide any desirable name for the new rule you create.
• Click Finish and execute all the steps again after choosing Outbound Rules in place of Inbound Rules.

Step 2- Creating Firewall Exceptions for QB Executable (.exe) Files

QuickBooks Desktop has a set of executable files that run in the background to ensure the software runs smoothly and gives the desired output. You must also prevent them from getting blocked by the Windows Firewall by adding exceptions as shown below-

• Open the Windows Defender Firewall settings window from the search bar or the Control Panel as you did earlier.
• Click the Inbound Rules option and tap New Rule in the next window.

• Select Program and click Next.
• Choose This Program Path option and use the below table to enter one or more of QB files-

• After entering the QB executable file, click Allow the connection and select all the profiles mentioned in the software prompt.
• Name the new rule you create and repeat the steps after choosing Outbound Rules instead of Inbound Rules.

Step 3- Prevent QB and DBSM Files from Getting Blocked by the Antiviruses

After configuring the Windows Defender Firewall settings, it is also necessary to make sure that QuickBooks or Database Server Manager files aren’t blocked by the antiviruses on your system. For this, you’ll have to open your antivirus and check its blacklisted programs list to find QB files. Then, remove any of the QB executable files (mentioned in the table above) from the quarantined programs list of the antivirus. Disabling antivirus while setting up the multi-user network is another way you can safeguard QB files.

We tried simplifying all the troubleshooting methods to the extent that you can easily execute them to remove QuickBooks error code 6120, 0. It is expected that you apply all the methods precisely, and the company file error is terminated from your QuickBooks.
