Access denied when remotely trying with Get-NlbClusterNode

Question

When I locally, on the SMTP Cluster run this command:
Get-NlbClusterNode 
I get the output I need.
But if I try the same from a remote server (same network and domain) I get an:
[smtp-s001a]: PS C:\> Get-NlbClusterNode 
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) 
+ CategoryInfo          : 
+ FullyQualifiedErrorId : 
AccessDenied,Microsoft.NetworkLoadBalancingClusters.PowerShell.GetNlbClusterNode 
Why is that? It is ONLY the "Get-NlbClusterNODE" command that gives me access is denied. "Get-NlbCluster" for an example, works just fine.
 I am connecting as a Domain Administrator (which is a member of the Local Administrators Group on every node). Same account used remotely when I log on locally, where it works locally.
Any advice?

I run this script now:
cls
Import-Module NetworkLoadbalancingClusters -ErrorAction Stop
Write-Host "Every thing works fine"
Get-NlbClusternode
Get-ChildItem \\zserver\c$
Output:
Every thing works fine
