Hi,
I have 2 Windows Server 2025 machines: Server A is standalone, not AD joined and not AzureAD joined. Server B is AzureAD joined but not AD joined. I'm trying to connect to a file share on server B from server A. I ran a net use command with the hostname of server B, with an AzureAD user which is a local admin on server B. I tried the following username formats:
AzureAD\user@mytenant.onmicrosoft.com
AzureAD\user
user@mytenant.onmicrosoft.com
I always get an error: "The user name or password is incorrect.". Looking at the event logs on server B, I see authentication failures for this user, with authentication package NTLM, which seems wrong.
How can I make this work? Thanks!

What happens if you execute this?
$cred = Get-Credential # Enter AzureAD\user@mytenant.onmicrosoft.com and password New-PSDrive -Name Z -PSProvider FileSystem -Root "\\ServerB\Share" -Credential $credCheers

2024-12-15T07:54:07.66+00:00 Thanks @Marti Peig ,
I was trying to reproduce a customer issue, but my first understanding was wrong - it turns out that both machines are AAD joined. When I try to reproduce it with 2 AAD joined machines, it does work (using AzureAD\user@mytenant.onmicrosoft.com), so I need to try and understand what's different in the customer's environment.
I have a similar but different issue, I'll open a separate thread for that.

If you are encountering authentication failures with the NTLM authentication package, it is possible that the file share is not configured to allow Kerberos authentication. You can check the file share configuration to ensure that it is configured to allow Kerberos authentication.
If you are still unable to connect to the file share, you may want to check the network connectivity between the two machines. Ensure that the machines can communicate with each other over the network and that there are no firewalls or other network devices blocking the traffic.
Thanks,
Navya.
