Server is running off of Windows Vista SP1 x64 with XAMPP

The function was available in windows from php 5.3.0.  If your php is older than that, you can use the pear package Net_DNS.

 

Details are in the manual: checkdnsrr()

I am using 5.2.8. I am using xampp so it is for a linux distro. I do not see any other version of php other than the version i have on their site.

It maybe for a linux distro, but versions before 5.3 did not have the right functionality of that function for windows, unfortunately.

 

function win_checkdnsrr($host, $type='MX') {
    if (strtoupper(substr(PHP_OS, 0, 3)) != 'WIN') { return; }
    if (empty($host)) { return; }
    $types=array('A', 'MX', 'NS', 'SOA', 'PTR', 'CNAME', 'AAAA', 'A6', 'SRV', 'NAPTR', 'TXT', 'ANY');
    if (!in_array($type,$types)) {
        user_error("checkdnsrr() Type '$type' not supported", E_USER_WARNING);
        return;
    }
    @exec('nslookup -type='.$type.' '.escapeshellcmd($host), $output);
    foreach($output as $line){
        if (preg_match('/^'.$host.'/',$line)) { return true; }
    }
}

 

There is some code you can use in place of checkdnsrr for Windows.
