mapping drive: System error 64 has occurred

Question

Hello all, when I run the command to map my storage account on to my on-premises virtual machine I get the error:

PS C:\Windows\system32> net use j: \<STORAGE ACCT>.file.core.windows.net\share
System error 64 has occurred.
The specified network name is no longer available.

• The OS is Windows 10 21H1 with SMB 3.1
• The on-premises machine is joined to the on-premises AD which is sync'd with Azure AD Connect to the Azure AD.

For troubleshooting I run the following command:
Debug-AzStorageAccountAuth -StorageAccountName $StorageAccountName -ResourceGroupName $ResourceGroupName -Verbose
===> OUTPUT:
Name Result

@Jai Ragoo Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

If you have a proxy or any other kind of NAT device in his Local Network, that would be blocking the connection from On-Prem to Azure for map the Azure File Share

• Add the IP Address for the Storage Account or range (x.x.x.0/24) in the proxy or NAT device.
• ipconfig /flushdns & ipconfig /registerdns (Elevated cmdline)
• Control Panel -> Administrative Tools -> Local Security Policy
• Under Security Settings -> Local Policies -> Security Options Set "Microsoft network client: Digitally sign communications: Disable (Enabled by default)

Hope this helps
