Powershell remote connect to DPM not working

Question

Hello all,
Using System Center DPM 2012 R2.
Trying to start with automation in SMA using our DPM servers. Tried to use the sample script
"Sample-Managing-DataProtectionManager", this is a simple script with a connect-DPMServer statement. When executing keep getting the error "Connect-DPMServer Unable to connect .. ID: 948". Verify that the DPM service is running on this computer.
Pretty sure that DPM services are running. Using an account with domain admin rights and full access to the DPM server (local admin) and SQL Server instance (sysadmin) hosting the
DPM db's. And firewalls allow access (tried with firewalls off).
When I try to connect to one of the DPM servers from a remote DPM Management shell all works fine. When I try to simulate the inlinescript (used by SMA) with an invoke-command
from a remote
host I get the same error. Tried starting PowerShell as administrator, but still no luck. Tested if the invoke-command was running as administrator and elevated, this is the case.
I get the feeling that I am missing something :-). Anyone any luck with using dpm from sma or using powershell from a remote host to connect to a DPM server and can help me?
Kind regards,
Erwin

Hi Adrian,
Finally got it working, but not that easy. SMA is using workflow and you can't use New-PSSession in a workflow. You need to use inlinescript then. And then you have to workout how to use your variables.
Below my working example. Thx for your assistance!
workflow Managing-DataProtectionManager
# Connection to access DPM server.
$DpmConnection = Get-AutomationConnection -Name 'DpmConnection'
$DpmServer = $DpmConnection.ComputerName
"Using script host $DpmServer"
# Create a PSCredential from the 'Username' and 'Password' fields within
# 'DpmConnection' because this is the form of authentication that an
# inlinescript accepts.
$SecurePassword = ConvertTo-SecureString -AsPlainText -String $DpmConnection.Password -Force
$DpmCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $DpmConnection.Username, $SecurePassword
inlinescript {
$sesOption = New-PSSessionOption -SkipCACheck -SkipCNCheck -SkipRevocationCheck
$ses = New-PSSession -ComputerName $Using:DpmServer -Credential $Using:DpmCredential -Authentication CredSSP -SessionOption $sesOption
Invoke-Command -Session $ses -ScriptBlock {
param($DpmSrv)
# Import DPM module.
Import-Module DataProtectionManager
# Connect to DPM server.
Connect-DPMServer -DPMServerName $DpmSrv
# Obtain a list of disks found on DPM server.
#Get-DPMDisk
Get-DPMBackupNetworkAddress
} -ArgumentList $Using:DpmServer
Remove-PSSession -Session $ses
} -PSComputerName $DpmServer -PSCredential $DpmCredential
