5 years agoReplace IP by DNS Name
Hello,
I got from Eric and Josh a script which is having the basic code to do the task I need. I would like to replace the IP Address/DNS Name by the DNS Name for all our servers.

foreach ($hostname in $results.items) {
$sysname = (($hostname.systemProperties) | Where-Object -Property "Name" -eq "system.sysname").value

$newName = $sysname.split(".")[0]
} else {
$newName = $sysname
}
if ($hostname.Name -eq $newName) {
Write-Host "Name `"$($hostname.displayName)`" matched no change needed"

$httpVerb = 'PATCH'
$resourcePath = "/device/devices/$($deviceId)"

Name = $newName
} | ConvertTo-Json
Send-Request $resourcePath $httpVerb $queryParams $data
Write-Host "Changed host id $($hostname.id) Name from `"$($hostname.ips)`" to `"$newName`"."
}
}
but for now I am getting an error:
Request failed, not as a result of rate limiting
StatusCode: 404
StatusDescription: NotFound
LM ErrorMessage HTTP 404 Not Found
LM ErrorCode 1400
Any idea of the issue?
Test in progress
Thanks,
