Description:
------------
I am having trouble connecting to my MS SQL database from an external network address.  When I am at work connecting locally this code works fine.  When I am outside the building, it fails with the error mentioned in "Actual Result".  It does not appear to be a IP or a firewall issue because I can connect with the query analyser and other MS tools just fine.  Seems like some sort of network transport issue.  I can work around it using the COM example listed on the MS SQL documentation/user comments but I have libraries build around the SQL functions that I would rather use if I can figure this out.  I am mainly asking to try to determine why this function would act different in different network scenarios.

Reproduce code:
---------------
<?php
//Note: I am not disclosing my authentication for obvious reasons but my original code did have real quoted values.
mssql_connect(MY_IP, MY_UNAME, MY_PASS)
     or die('Error connecting');
echo 'success'
?>


Expected result:
----------------
success

Actual result:
--------------
Warning: mssql_connect(): Unable to connect to server: 68.111.105.35 in e:\bigdogdealer.net\bigdogmotorcycles.net\php\dealer\test.php on line 10
