  • Choose “Allow the Connection” and then “Next.”
  • Select all profiles if asked, then click “Next.”

  6. Find and select one of the executable files in the table given below and then select Next.
  7. Select Allow the Connection and then select Next.
  8. Ensure all profiles are marked and then choose Next.
  9. Create a rule and name it.

Create Outbound rules by following the same above-mentioned steps. The only difference would be, choosing Outbound rules instead of Inbound rules in step 3. Otherwise, everything will be as it is.

Solution 4: Ping IP and Hostname on the Server

Test the connection between your server and workstation by pinging as follows:

Step 1: Enable Network Discovery on your server and workstations

  • Go to the Windows Start menu on both the server and workstations.
  • Search for “Network” and access the Network and Sharing Center.
  • Select “Change advanced sharing settings.”
  • Make sure to enable “Turn on network discovery” in the Network Discovery section. Also, enable “Turn on file and printer sharing” in the File and Printer Sharing section.

Step 2: Obtain your server’s name from the server

  • Access the server computer’s Windows Start menu.
  • Search for “Run” and open the Run dialogue.
  • Type “CMD” in the Run window and select Enter.
  • Input “ipconfig/all” in the CMD box and press Enter.
  • Note the Host Name in the Windows IP Configuration section; this is your server name, located on the right-hand side.

Step 3: Return to your workstation to test the server

  • Open the Windows Start menu on the workstation.
  • Search for “Run” and open the Run dialogue.
  • Enter “CMD” in the Run box and hit Enter.
  • Type “ping [your server name]” (without brackets) and press Enter.

If you receive a response for each packet without any loss, your server functions correctly, and you can explore other solutions.

Now, enable hosting and verify the Network Diagnostics Failed error.

Solution 5: Create “fixquickbooks.bat”

Microsoft DNS Server can sometimes use the UDP ports 55368, 55369, 55370, 55371, and 55372, and QuickBooks needs those ports.

  • Log in as a Domain Administrator and then create a text file on the desktop called fix QuickBooks.
  • Copy the information below between the equals section and paste it into that file.

REM This needs to run in the server or there is a DNS conflict that causes the Network Diagnostics to fail.

netsh int ipv4 add excludedportrange protocol=udp startport=55368 numberofports=5
net stop "DNS Server"

net stop "QuickBooksDB28"
net start "QuickBooksDB28"
net start "DNS Server"

  • When the file is opened in the Notepad, select File and then Save as.
  • Now, consider saving the file to the desktop and type “fixquickbooks.bat” in the filename type. It’ll make a batch file.

Note: Don’t forget to give the quotation marks as part of the filename.

  • Now, right-click the batch file and select Run as administrator.
  • Now, you can go to any computer over the network or you can also go to the server computer to launch QuickBooks. It is important to know that it is fixed until it happens again.

Note: From now onwards, right-click the fixquickbooks.bat file and Run As Administrator. Another key point is that people might forget to run it as an administrator. So, consider renaming the batch file from fixquickbooks.bat to “Right-Click and run as Administrator-fixquickbooks.bat” to help them remember.
