Windows sysprep static ip address

I did it by editing the unattended answer file applied to the VM I created.  I created a generic answer file and replace the tags with the settings I choose.

# Setup the customization spec for the sysprep unattend answer file
$CustSpec = New-NTNXObject -Name VMCustomizationConfigDTO
$BaseFile = Get-Content "WADK-TMG-BASE.xml"
$AnswerFile = $BaseFile.Replace("xxxHOSTNAMExxx",$VMName).Replace("xxxIPADDRESSxxx",$VMIP).Replace("xxxNETMASKxxx",$VMNM).Replace("xxxGATEWAYxxx",$VMGW).Replace("111DNS111",$DNS[0]).Replace("222DNS222",$DNS[1]).Replace("333DNS333",$DNS[2])
$CustSpec.userdata = $AnswerFile

This is what the xml file looks like:
