Powershell script - Rename computer and join domain

I had to automate the process. I used the following script:

$hostname = read-host 'hostname'
$Domain = 'domain.com'
$Credential = Get-Credential

Rename-Computer $hostname
Add-Computer -Domain $Domain -NewName $hostname -Credential $Credential -Restart -Force

if you also need to setup ip:

$ipaddress = read-host 'enter new ip'
$gateway = read-host 'gateway:'
$prefix = read-host 'prefix (ie 24):'
$dns1 = read-host 'dns 1'
$dns2 = read-host 'dns 2'
New-NetIPAddress –IPAddress $ipaddress  -DefaultGateway $gateway -PrefixLength $prefix -InterfaceIndex (Get-NetAdapter).InterfaceIndex 
Set-DnsClientServerAddress -InterfaceIndex (Get-NetAdapter).InterfaceIndex -ServerAddresses ($dns1, $dns2)

$hostname = read-host 'hostname'
$Domain = read-host 'domain'
$Credential = Get-Credential

Rename-Computer $hostname
Add-Computer -Domain $Domain -NewName $hostname -Credential $Credential -Restart -Force
