I'm trying to connect to connect to an Azure Files share using Powershell, but it's failing, so am going through each command to try and locate the issue. Searching online, it seems that I need to verify port 445 is open (which my Bitdefender firewall has been configured to allow).
I ran this command in Azure Powershell to test:
Test-NetConnection -Port 445 -ComputerName https://myazurefileshare.file.core.windows.net
The error was:
WARNING: Name resolution of https://myazurefileshare.file.core.windows.net failed
I then opted for something more generic, using port 80 as a test (sorry Microsoft):
Test-NetConnection -Port 80 -ComputerName https://www.microsoft.com
Surprisingly, this also failed:
WARNING: Name resolution of https://www.microsoft.com failed
I'm new to Powershell, so please excuse any RTFM oversights. However, can anyone please shed any light on this? I'm simply trying to verify that port 445 is open.

have you triedTest-NetConnection -ComputerName "www.google.com"from that server and checked that issue is not related to the dns server . You can assign 8.8.8.8 as a secondary dns in the server and see what is the output.

So that means there is no issue on the command or the connection. It is pure the site that you are using and the corresponding DNS resolution. Try adding an A record in the resolv.conf or adding the entry in the hosts file and see. Also ignore the warning that you are getting for microsoft.com -- that is a separate thing. Could be a microsoft forwarder thing.

The original error properly happens because you have typed the wrong format of the parameter -ComputerName for use Test-NetConnection. The ComputerName specifies the Domain Name System (DNS) name or IP address of the target computer.
In this case, the computer name should be an FQDN of your storage account. So you could use Test-NetConnection -Port 445 -ComputerName somestoragexxx.file.core.windows.net to verify the port 445.
Test result on my side, name resolution works successfully but TCP 445 connection has a failure.
The same test result as the script MS provided.

It turns out the port was open after all (so cue another question later...). Microsoft have a troubleshooting script which is way more powerful at mounting the drive than the default script available within the Azure Files "Connect" link, see Troubleshooting tool for Azure Files mounting errors on Windows.
I saved AzFileDiagnostics.ps1 to my desktop for the purposes of the following example. Sadly it won't run without unblocking first because it's not digitally signed, so the full Powershell script I had to run was:
> Unblock-File -Path "C:UsersMyNameDesktopAzFileDiagnostics.ps1"
> C:UsersMyNameDesktopAzFileDiagnostics.ps1
The script then presents various parameter prompts that you need to complete, such as the storage name, etc. However, the key check is the port check - this returned okay for me:
======Validate Storage Account Name resolution
[OK]: Storage Account Name myazurefileshare.file.core.windows.net is
resolved to 51.140.232.124
======Validate port 445 reachability over Storage Account IP 51.140.232.124
[OK]: Connection attempt succeeds - Port is open
[OK]: Validation steps do not return any errors
