The key to doing this is loading the SharePoint DLLs into your PowerShell environment. You can do this using the System.Reflection.Assembly class. Take a look at this sample script:

param( $newTimeout = 600 )

[System.Reflection.Assembly]::Load("Microsoft.SharePoint.Publishing, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c")

$cdconfig = [Microsoft.SharePoint.Publishing.Administration.ContentDeploymentConfiguration]::GetInstance()

$cdconfig.RemoteTimeout = $newTimeout
$cdconfig.Update()

"Updated RemoteTimeout to $newTimeout seconds."

In line 3, I load up the Microsoft.SharePoint.Publishing DLL, then I grab the ContentDeploymentConfiguration (line 5) using the GetInstance() static method. I update the RemoteTimeout property, then call Update(), and we’re done. No code to write and compile.

This example uses the param keyword, which means you can save it as ChangeRemoteTimeout.ps1, then run it like this:

PS C:\> ChangeRemoteTimeout –newTimeout 1200

This is completely optional, of course, but if you find yourself doing this a lot, it might be worth saving it as a reusable script.

You might also want to make changes to some of the options that are exposed through the UI already. Here’s an example:

PS C:\> [System.Reflection.Assembly]::Load("Microsoft.SharePoint.Publishing, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c")
PS C:\> $cdconfig = [Microsoft.SharePoint.Publishing.Administration.ContentDeploymentConfiguration]::GetInstance()
PS C:\> $cdconfig.AcceptIncomingJobs = $true
PS C:\> $cdconfig.RequiresSecureConnection = $false
PS C:\> $cdconfig.Update()

In this case, I’m configuring the farm to accept incoming deployment jobs and not require secure connections. You can also make additional changes to other properties, such as FileMaxSize and RemotePollingInterval using this method. Stefan covers these properties in his Pimp My Content Deployment Job post.

One other note… Using .NET DLLs in PowerShell is generally supported across the board. It’s not limited to the SharePoint DLLs. There’s some pretty exciting stuff you can do here once you start playing around.
