PowerShell WSUS v3 Start Sync script

OK so I got the srcipt for Powershell that starts a Synchronization. Work
fine if you run it from a WSUS (v3.0) server however if you try and change
the 'GetUpdateServer()' value to look at a downstream server all I get is
'Unable to connect to the remote server'. For the life of me I can't figure
out why.

Heres the script
[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Ad ministration") | Out-Null
$wsus =
[Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer("ServerName","false");
$wsus.GetSubscription().StartSynchronization();

Heres the output:
Exception calling "GetUpdateServer" with "2" argument(s): "Unable to connect
to the remote server"
At g:\Source\Scripts\Development\WSUS\StartSync.ps1:1 1 char:78
+ $wsus =
[Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer( <<<<
"scocdc01p","false");
You cannot call a method on a null-valued expression.
At g:\Source\Scripts\Development\WSUS\StartSync.ps1:1 2 char:22
+ $wsus.GetSubscription( <<<< ).StartSynchronization();

Just to confuse things more we are using the alternate port (8530) because
the default port is already in use.

Any help would be great.

for a wsus server using port 8530

Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer("ServerName","false",8530);

You were really close.
