How to run a powershell script as a domain Administrator

Vagrant
2

I add my scripts in case it helps:

Vagrantfile:

-------------------------------------------------------------

Exchange Server - waterfalls

-------------------------------------------------------------

config.vm.define “waterfalls” do |exch|
exch.vm.hostname = “waterfalls”
exch.vm.network “private_network”,

virtualbox__intnet: “intnet-target”,
auto_config: false
#exch.winrm.username = “Administrator”
#exch.winrm.password = “vagrant”

exch.vm.provider "virtualbox" do |vb|
  vb.name = "waterfalls"
  vb.memory = 8192
  vb.cpus = 4
  vb.linked_clone = false
  vb.customize ["modifyvm", :id, "--vram", "128"]
