MSSQL not working NT4/IIS4/MSSQL6.5

I installed IIS, MySQL and php on my Win 2000 machine, set the variables in php.ini. When i do a phpinfo(); it returns that MSSQL is active I then installed php on the company NT Server with IIS and MSSQL. When I do a phpinfo(); MSSQL is nowhere to be seen I copied my php.ini from the 2000 machine to the NT machine, restarted IISAdmin, still not there. Why would it work on 2000 but not NT? I set them both up the same way. If I run the script from my local webpage trying to connect to the database on the NT Server I get "unable to connect to database, blah,blah,blah...not a trusted user" which I know is a privledges problem, but the MSSQL command was sent. If I run it from the NT webpage I get "Fatal error: Call to undefined function: mssql_connect()" which is a PHP setup problem. $db = mssql_connect("NTS1", "wwwguest", "guest"); if(!$db){echo("Unable to connect to database server.");exit();} if(! @mssql_select_db("bruin")){echo("Unable to select database.");mssql_close();exit();} Any and all suggestions would be appreciated Thanks all
