php socket socket_create blocks

[gilit golit]

Hi
when I do
$socket=socket_ create(AF_INET, SOCK_STREAM, SOL_TCP))
it blocks. Nothing happens.
here is the code :
I copied it from php.net
I am using webmatrix , and IIS , Not apachi. maybe this causes the problem

error_reporting(E_ALL);

set_time_limit(0);

ob_implicit_flush(); 


$address = '192.168.0.233';              

$port = 1000;
echo "address is : $address --- <br/><br/><br/>" ;

echo "before socket_create ... <br/> " ;
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) ;
echo "after socket_create <br/> " ;

The output displayes : before socket_create ...
and then, nothing happens
