checkdnsrr() trouble

[xkesterx]

im having trouble using the checkdnsrr() function locally, when uploaded to the server i use its fine, but locally it doesnt work

this is the code on line 30

if (! checkdnsrr($domain, "MX"))

it then goes on to say error if one isnt resolved but thats not the problem

the problem is when i try to run it all it says is this

Fatal error: Call to undefined function: checkdnsrr() in c:\inetpub\wwwroot\ddrc2\email\check.php on line 30

i think it might be sumthing to do with the way i have php setup but im not sure, any help would be appriciated

this comes from PHP.net manual :

Note: This function is not implemented on Windows platforms. Try the PEAR class Net_DNS.

as i can see by your path, you're using a windows server.
that's why it doesn't work .
