Your question I have miss it,before I think,
it's problem of my server,but not.
When we use a remote server,the server of username and password have changed,so no root access.
Now,you must know the server of username and password,or IP,then you can connect to the server.
Exp:linux+SQL Server+PHP 4.0
$string=mssql_connect'202.114.8.8','username','password')
