使用Powershell实现计算机名称及IP地址修改

我的第一篇博客分享，写这个代码的用途是在公司Ghost完系统之后去修改本地计算机名称及IP 地址，用Powershell实现。

1. 代码第一部分，检查Powershell是否已管理员权限执行，如果不是的话，强制以管理员权限开启一个powershell窗口.

 #region Key code: force to run with administrator rights
 $currentWi = [Security.Principal.WindowsIdentity]::GetCurrent()
 $currentWp = [Security.Principal.WindowsPrincipal]$currentWi

 if( -not $currentWp.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator))
 {
   $boundPara = ($MyInvocation.BoundParameters.Keys | foreach{
      '-{0} {1}' -f  $_ ,$MyInvocation.BoundParameters[$_]} ) -join ' '
   $currentFile=(Resolve-Path $myInvocation.MyCommand.Source).Path

  $fullPara = $boundPara + ' ' + $args -join ' '
  Start-Process "$psHome\powershell.exe"   -ArgumentList "$currentFile $fullPara"   -verb runas
  return
 }
 #endregion

2. 第二部分，调用.NET Framework创建一个窗口输入新的computer name，之后重命名

 #access .NET Framework
 [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic') | Out-Null
 # config Computer Name
 $computer=[Microsoft.VisualBasic.Interaction]::InputBox("Please enter a computer name. Standard names can contain letters (a-z, a-z), Numbers (0-9), and hyphen (-).", "Computer Name", "$env:computername")
 Rename-Computer -NewName $computer
 # end of configure Computer Name

3. 第三部分, 因为ghost后的系统网络名称不是原来的Local Area Connection，而会变成Local Area Connection #2类似这样后边跟数字的名称，所以我们需要调用gwmi组件并且正则表达式去匹配并选定网络名称包含Local Area Connection 的adapter，然后再去set ip地址.

 # Configure the local network IP address
 $IP=[Microsoft.VisualBasic.Interaction]::InputBox("Please enter the IP address, such as 192.168.1.1", "IP Address",'192.168.1.2')
 $parttern="^Local Area Connection"
 $NICs=gwmi win32_networkadapter `
 | Where {$_.NetConnectionID -match $parttern}
 foreach($NIC in $NICs) {
 $N=$NIC.NetConnectionID
 netsh interface ip set address name="$N" source=static addr=$IP
 }
 if($Error.Count -eq 0) {
 echo "Set OK!!!!"
 }
 Write-Host  'Press any key to exit ...'
 Read-Host
 # end of configure the local network IP address

4. 最后附上代码实现截图:
