if statement doesn't seem to work in the above script, I'm unable to ascertain where im doing wrong, all im trying to do is run the #### POST-RENAME DETAILS ### commands if " ( if Test-Connection -Computername $NewServer -BufferSize 32 -Count 10 -ea 1 -quiet)" newserver name which got renamed gets at least one successful ping.

Any help please 🙂 TIA

If statements always need an opening curly bracket { and closing } as you can see in the examples of the Microsoft documentation for If here https://technet.microsoft.com/en-us/library/Hh847876.aspx and below:

`
$a = 3
if ($a -gt 2)
{
Write-Host "The value $a is greater than 2."
}
`

If modified to your code to use opening and closing curly brackets for your If statement:
`
$cred = Get-Credential
$getinfo = Import-Csv C:\Users\Soma\Desktop\COMPUTERS.csv
$getinfo | foreach {
$OldServer = $_.Oldserver
$NewServer = $_.NewServer

I hope above helps.

Thank you Daniel, good catch I missed the curly, however even after placing the curly the code is not giving the desired out put.

I dont know why it is not collecting the new server name details. at this point " Rename-Computer -ComputerName $OldServer -NewName $NewServer -DomainCredential $cred -Restart -Confirm " the computer will be restarted.

and this " if (Test-Connection -Computername $NewServer -BufferSize 32 -Count 10 -Quiet) " should ping or test the connection connection and if responds atleast to one ping, it should proceed with " {

Write-Output '############# FLUSH_DNS #############'

ipconfig.exe /flushdns .............. }

it should ping the new computer name -Count 10 or wait until its up and collect the

" {

Write-Output '############# FLUSH_DNS #############'

ipconfig.exe /flushdns .............. }

but its not happening 🙁

Your computer may not restart in the time taken by Test-Connection to send 10 'pings'

run the code manually and see how long it takes to restart. You could swap your original version of the if statement for this

while ($true){
if (Test-Connection -Computername $NewServer -Count 1 -Quiet) {

break
}
}

which keeps testing until it gets a reply
