remote mssql 2008 connection issue - php

Question

I am having issues connecting to a mssql server that is located on a network machine. I need to connect remotely through another domain example (abc.com) not on the network to access data. This domain runs mysql if that makes any difference. I am trying to access the mssql server through this php script:
<?php
$server= 'ip address:port';
$user='user';
$password= 'pass';
$con = mssql_connect($server,$user,$password);
if (!$con)
{
die('Could not connect:' . mssql_get_last_message() );
}
else{ echo 'connected';
}
I run this script through the shell on abc.com and I get:
mssql_connect(): Unable to connect to server:
I have gone through several tutorials to enabling tcp/ip access through the sql server config manager as well as allowing the specific port through the firewall.
What are some other things I should try or steps I am missing here.
Also: the ip address I am using is the one I found in the sql server config manager-> protocols for SQLEXPRESS->tcp/ip_>ip addresses->IP2->ip adress it is the correct ip address? Where can I find it if not? I am not using the localhost 127.0.0.1

3. started sqlcmd Utility with -s \SQLEXPRESS to get the right sever-instance
C:\Program Files\Microsoft SQL Server\100\Tools\Binn
4. Go to SMSS and local sql instance properties -> Connections -> check "Allow remote connections to this server" and run this script.
