Automate Forest trust creation
Just a quick note: In case you were not aware - netdom.exe cannot create a Forest trust (inbound or outbound). But you can leverage the S.DS namespace to automate this with a little powershell:
$targetForestName = "targetForest.local"
$trustPassword = "PassWord123!23"
$TrustDirection = "Outbound" # see https://msdn.microsoft.com/en-us/library/system.directoryservices.activedirectory.trustdirection.aspx
$Forest = [System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest()
or both sides:
Hope it helps someone
