title: Failed to start WinNAT service
body: <p>How Resolved this problem ? </p>
  
  <p>I try make switch using a nat network.
  (from this link: <a href="https://www.thomasmaurer.ch/2016/05/set-up-a-hyper-v-virtual-switch-using-a-nat-network/" rel="nofollow noreferrer">https://www.thomasmaurer.ch/2016/05/set-up-a-hyper-v-virtual-switch-using-a-nat-network/</a> )</p>
  
  <p>I made:</p>
  
  <p><code>New-VMSwitch –SwitchName “NAT_vSwitch” –SwitchType Internal</code></p>
  
  <p><code>New-NetIPAddress –IPAddress 172.100.100.1 -PrefixLength 24 -InterfaceAlias "vEthernet (NAT_vSwitch)"</code></p>
  
  <p>but when I make this line:</p>
  
  <p><code>New-NetNat –Name NetworkNAT –InternalIPInterfaceAddressPrefix 172.100.100.0/24 </code></p>
  
  <p>My Output in PowerShell looks like:</p>
  
  <p><code> New-NetNat : Failed to start WinNAT service
  At line:1 char:1
  + New-NetNat –Name NetworkNAT –InternalIPInterfaceAddressPrefix 172.100 ...
