Using PSCredential Object to authenticate commands non-interactively

Question

I am using the PSCredential Object to authenticate a command, which I need to be run as a different user. I get the following on the powershell cli.

> whoami
dmn1\srveikafka
> $secpasswd = ConvertTo-SecureString "mypassword" -AsPlainText -Force
> $mycreds = New-Object System.Management.Automation.PSCredential ("srveizookeeper", $secpasswd)
>
> $sess = new-pssession -computername remotecomputer.xyz.com -credential $mycreds
> invoke-command -session $sess -scriptblock {whoami}
dmn1\srveizookeeper

But when I run these same commands as a powershell script I get this error.

new-pssession : [remotecomputer.xyz.com] Connecting to remote server remotecomputer.xyz.com failed with the following
error message : Access is denied. For more information, see the about_Remote_Troubleshooting Help topic.

Invoke-Command : Cannot validate argument on parameter 'Session'. The argument is null or empty. Provide an argument
that is not null or empty, and then try the command again.

    + CategoryInfo          : InvalidData: (:) [Invoke-Command], ParameterBindingValidationException

What am I getting wrong or missing?

您可能需要将域作为用户名的一部分包含在凭据构造函数中：

$mycreds = New-Object System.Management.Automation.PSCredential ("dmn1\srveizookeeper", $secpasswd)
