Powershell New-PSSession issue

When I remote desktop to a box I will get a prompt like this:

Once I select "Yes" I am connected to the box. When I try to login to the same box with the same credentials in PowerShell I get the error listed at the end of this post.

$secPasswd = ConvertTo-SecureString $password -AsPlainText -Force
$creds = New-Object System.Management.Automation.PSCredential($username, $secPasswd)
$session = New-PSSession –ComputerName $hst -Credential $creds

where $hst is "MyBox" and $username is "MyBox\MyUser"

Q: Is there a way in powershell for me to mimic the selection of the "Yes" button?

ERROR:

New-PSSession : [MyBox] Connecting to remote server MyBox failed with the following error message : WinRM cannot process the request. The following error with errorcode 0x80090311 occurred while using Kerberos authentication: There are currently no logon servers available to service the logon request.

Possible causes are:

• The user name or password specified are invalid.
• Kerberos is used when no authentication method and no user name are specified.
• Kerberos accepts domain user names, but not local user names.
• The Service Principal Name (SPN) for the remote computer name and port does not exist.
• The client and remote computers are in different domains and there is no trust between the two domains.

After checking for the above issues, try the following:

• Check the Event Viewer for events related to authentication.
• Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or use HTTPS transport.

Note that computers in the TrustedHosts list might not be authenticated.

• For more information about WinRM configuration, run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting Help topic.

Analysis on target box

• WinRM is running

• Expected firewall rules are in place

• User is part of the admin group

• PSRemoting is enabled
