database is not supported by PHP. anybody know the sol?

[Nidhi Yadav]

I have php 5.0 , sqlserver 2005,IIs5.0 when I am trying to install mantis it gives the error :" database is not supported by PHP. Check that it has been compiled into your server."
I have made following changes to config_inc.php
$g_hostname = "AITHENT231\SIMBAINT";
$g_db_username = "sa";
$g_db_password = "admin";
$g_database_name = "bugtracker";
$g_db_type = "mssql";
do php works with SqlServer?
Can any body tell what i am missing?

Yes,
it works... install freetds, compile php with freetds !

And I use ip&port instead of hostname

$g_hostname ='ip:port';
