Hi there,
I have to print input computer name (address) and alias name (if present) in following script with each iteration to fetch the DNS lookup for the bulk server provided in text file.
$InputFile = 'C:\computer.txt'
$addresses = get-content $InputFile
$reader = New-Object IO.StreamReader $InputFile
while($reader.ReadLine() -ne $null){ $TotalIPs++ }
write-host ""
write-Host "Performing nslookup on each address..."
foreach($address in $addresses) {
## Progress bar
$i++
$percentdone = (($i / $TotalIPs) * 100)
$percentdonerounded = "{0:N0}" -f $percentdone
Write-Progress -Activity "Performing nslookups" -CurrentOperation "Working on IP: $address (IP $i of $TotalIPs)" -Status "$percentdonerounded% complete" -PercentComplete $percentdone
## End progress bar
try {
[system.net.dns]::resolve($address)| Select HostName,AddressList
}
catch {
Write-host "$address was not found. $_" -ForegroundColor Green
}
}
write-host ""
write-Host "Pinging each address..."
foreach($address in $addresses) {
## Progress bar
$j++
$percentdone2 = (($j / $TotalIPs) * 100)
$percentdonerounded2 = "{0:N0}" -f $percentdone2
Write-Progress -Activity "Performing pings" -CurrentOperation "Pinging IP: $address (IP $j of $TotalIPs)" -Status "$percentdonerounded2% complete" -PercentComplete $percentdone2
## End progress bar
if (test-Connection -ComputerName $address -Count 2 -Quiet ) {
write-Host "$address responded" -ForegroundColor Green
} else
{ Write-Warning "$address does not respond to pings"
}
}
write-host ""
write-host "Done!"
