Installing SQL Server 2012 remotely via Powershell using Invoke-Command

Question

I am trying to perform a SQL Server 2012 command line installation using Powershell Invoke-Command on Windows 2012 Datacenter.
The code I am using is as follows:
 $ret = Invoke-Command -ComputerName $COMPUTER -ArgumentList $MEDIA,$ACTION,$FEATURES,$INSTALLDIR,$INSTANCEID,$INSTANCENAME,$SQLDATADRIVE,$SQLLOGDRIVE,$DOMAIN,$SQLSERVERSERVICEUSER,$SQLSERVICEPASSWORD,$PRODUCTKEY,$SQLSERVERSA,$username,$ADMINPASSWD
-Credential $cred -ScriptBlock {
  param($MEDIA,
     $ACTION,
     $FEATURES,
     $INSTALLDIR,
     $INSTANCEID,
     $INSTANCENAME,
     $SQLDATADRIVE,
     $SQLLOGDRIVE,
     $DOMAIN,
     $SQLSERVERSERVICEUSER,
     $SQLSERVICEPASSWORD,
     $PRODUCTKEY,
     $SQLSERVERSA,
     $USERNAME,
     $PASSWD)
  Set-Location $MEDIA
  Import-Module ServerManager
  if (-not [IO.Directory]::Exists($MEDIA)){
   $hn = hostname
   return 0,"Failed to find SQL Server Installer at $MEDIA on $hn"
  $tran = ""
  Try{
   & $MEDIA\setup.exe /ACTION=$ACTION /Q /FEATURES=$FEATURES /IACCEPTSQLSERVERLICENSETERMS /UPDATEENABLED=False /INSTALLSHAREDDIR="$INSTALLDIR\Program Files\Microsoft SQL Server" /INSTALLSHAREDWOWDIR="$INSTALLDIR\Program Files
(x86)\Microsoft SQL Server" /RSINSTALLMODE="FilesOnlyMode" /INSTANCEID="$INSTANCEID" /INSTANCENAME="$INSTANCENAME" /INSTANCEDIR="$INSTALLDIR\Program Files\Microsoft SQL Server" /ENU="True" /AGTSVCSTARTUPTYPE="Automatic"
/SQLSVCSTARTUPTYPE="Automatic" /NPENABLED=1 /TCPENABLED=1 /RSSVCStartupType="Automatic" /ERRORREPORTING=0 /SQMREPORTING=0 /INDICATEPROGRESS /INSTALLSQLDATADIR="$SQLDATADRIVE\DATA" /SQLUSERDBDIR="$SQLDATADRIVE\DATA" /SQLUSERDBLOGDIR="$SQLLOGDRIVE\LOG"

/SQLCOLLATION="SQL_Latin1_General_CP1_CS_AS" /SQLSVCACCOUNT="$DOMAIN\$SQLSERVERSERVICEUSER" /SQLSVCPASSWORD="$SQLSERVICEPASSWORD" /AGTSVCACCOUNT="$DOMAIN\$SQLSERVERSERVICEUSER" /AGTSVCPASSWORD="$SQLSERVICEPASSWORD"
/ASSVCACCOUNT="$DOMAIN\$SQLSERVERSERVICEUSER" /ASSVCPASSWORD="$SQLSERVICEPASSWORD" /RSSVCACCOUNT="$DOMAIN\$SQLSERVERSERVICEUSER" /RSSVCPASSWORD="$SQLSERVICEPASSWORD" /FTSVCACCOUNT="NT AUTHORITY\LOCAL SERVICE"
/INDICATEPROGRESS > $out
  } Catch [System.Exception] {
   return 0,$_.Exception.ToString()
  if ($tran -ne ""){
   $out += $tran
  return 1,$out
The media resides on the server that I am remoting to in powershell and the server is on the same domain. The credentials I pass are for a Domain Admin, but SQL Server fails to validate the credentials for the passed parameter for the sql service user with
a Access Denied.
If I run the same command with the same user directly on the server it works fine.
My guess is that the elavated privs for Administrator are not being set when using Invoke-Command? Is there a way to utilize powershell to install SQL Server 2012 with command line option using the invoke-command and passing credentials? Or is this a limitation
to the SQL Server installer. If there is can a example be provided?

Ok, so with the help of some friends, we found a fix that works!
Prior to running the Invoke-Command I now run:
# enable CredSSP on a client computer; this command allows the client credentials to be delegated to the server01 computer.:
Enable-WsManCredSSP -Role Client -DelefateComputer server.some.domain.com
Then I add the -Authentication option to my Invoke-Command with option Credssp.
The install the works fine. Hope this helpes all.
