Does not support single label domains

[aut0pil0t]

DNS resolution check on Single Label Domains fail and the script does not continue. Adding the snippet below before the line [System.Net.Dns]::gethostentry($targetedADforestFQDN) | Out-Null and replacing targetedADforestFQDN with targettedDnsFqdn worked for me.

$targettedDnsFqdn = if ($targetedADforestFQDN -notmatch ".") {
$targetedADforestFQDN + "."
} else {
$targetedADforestFQDN
}
