Access denied when remotely trying with Get-NlbClusterNode

I have found some workaround. Impersonate with admin credentional in remote session

function EntryPoint()
{
    ImportModule-Impersonate;

    $impersonate = new-object UserSession.Impersonate;
    try
    {
        if ($impersonate.Login("SKODA", "Administrator", "*****") -eq $false) {
            throw new Exception("Invalid credentials");
        }
        Import-Module NetworkLoadBalancingClusters
        Get-NlbClusterNode;    
    }
    finally
    {
        $impersonate.Dispose();
    }
};

function ImportModule-Impersonate {

Also disable UAC and reboot machine.

I had the exact same issue. The user who was using those credentials to access and run Get-NlbClusterNode had the correct permissions, yet for some unexplicable reason he was getting that weird error. I gave up investigating and did the following workaround:

$username = "domain\user_name"
$securePassword = "secure_hash" | ConvertTo-SecureString
$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword
$result = Start-Process powershell.exe -WorkingDirectory $PSHome -Credential $credential -ArgumentList ("-File $PSScriptRoot\your-script.ps1") | Out-Null

Where if in your-script.ps1 you put in the:

Invoke-Command -ComputerName "your-remote-server" -ScriptBlock {
    Get-NlbClusterNode
    #Any other commands you want here
}

it worked as expected...
