Php con sql server

[zibor]

Hola Hice un programa (web) en php para contabilidad para la empresa en la q trabajo. Recoje los dato de una base de datos (sql server) de prueba q está en un ordenador (llamemosle 1), me funcionó las consultas y todo perfecto. Todo el problema me está dando ahora al acceder a la a la base de datos oficial, la q no es de prueba, que está en otro ordenador (llamemosle 2).
El programita que he hecho, está compuesto por un index.php (formulario para la consulta), iva.php(recoje los datos de la base de datos) y bd.php(es el que conecta con la base de datos y cierra la conexión). En este ultimo (bd.php) lo que he heco es cambiar la ip del ordenador 1 al q accedia a la base de datos de prueba y le he puesto la ip del ordenador 2 con su respectiva cuenta de usuario y contraseña de dicha base de datos, pero me sale errores, que creo que no tiene nada que ver con el codigo en si de php, espero ue puedan ayudarme porfavor.

Cito los errores:
