3. If you’re prompted, make sure all profiles are marked. Click Next again.
4. Create a rule and name it “QBPorts(year).”
5. After this, select Finish.
6. Re-perform the same steps to create outbound rules.

Step 2: Create Windows firewall exceptions for QuickBooks programs

QuickBooks uses executable files (.exe) to perform various tasks. To create exceptions for each executable on the table, adhere to the following steps:

1. Navigate to the Windows Start menu, enter Windows Firewall into the search box, and open Windows Firewall.
2. Select Advanced Settings.
3. Hit right-click on Inbound Rules and hit the New Rule tab.
4. Choose Program and then press Next.

8. If prompted, you need to verify that all profiles are marked. Later on, press the Next button.
9. Create a rule and name it “QBFirewallException(name.exe).”
10. And lastly, re-implement the same steps to create outbound rules.

Here’s a list of some executable files, along with their locations: 

Executable files	Location
IntuitSyncManager.exe	C:\Program Files\Common Files\Intuit\Sync

FileManagement.exe	C:\Program Files\Intuit\QUICKBOOKS YEAR

When you’re ready, open QuickBooks Desktop and try to access your company file in the Multi-user environment.

To switch from multi-user mode to single-user mode, adhere to the following steps:

1. Firstly, open QuickBooks and then navigate to the File menu. 
2. Select Switch to Single-user Mode/Switch to Multi-user Mode.
   
3. After this, a warning prompt will appear on your screen, asking you to confirm you want to switch to multi-user mode. Press OK.
4. Then, QuickBooks will close the company file and reopen it in the Multi-user network.
5. Now, you’re good to go.

1. Firstly, open QuickBooks on your workstations or servers.
2. Head to the File menu and then click on Utilities.

• Avoid selecting the Host Multi-User Access option if you see this; move to the next workstation. This one isn’t the problem.

4. Once done, choose the Programs settings and turn off the internet monitor feature.
5. If your computer has an ESET NOD32 antivirus application, you’ll have to give a new name to the file by adding .Old at the end of the extension.
6. Finally, launch the QuickBooks program once again and check for the error status. 

Method 4: Rename the .ND files to resolve network issues

.ND is the configuration file that allows QuickBooks Desktop to access/open the company file in a network or multi-user environment. When there’s an issue with your network data files or extensions, you won’t be able to open it in multi-user mode. To get access to a multi-user environment, change the name of the .ND files. 

Method 5: Use the QuickBooks Database Server Manager 

The QuickBooks database server manager creates Network Data Files (.ND Files) stored in the Host workstation, which helps you access multiple versions of QuickBooks Desktop in multi-user mode. If such network files get disconnected from your workstation, you won’t be able to open them on multiple workstations and end up with QuickBooks error 6010 100. To troubleshoot this, you need to download and run the QB database server manager on your system.
