Problem connect with SQL SERVER database

[Santanu Basak]

I am running a WinXP Pro w/ SP2 (my home computer)
Apache 2.2.11
MySQL 5.1.33
PHP 5.2.9

I have to connect a remote MSSQL database

IIS
MS SQL Sever 2005
I am getting error
Warning: mssql_connect() [function.mssql-connect]: message: Login failed for user 'NT AUTHORITY\ANONY MOUS LOGON'. (severity 14)


- I have ntwdblib.dll in my c:\apache2\bin &
c:\php folders (year 2000 version)


- I have extension=php_m ssql.dll in my php.ini

- when I run:

<?php

$host="mssql2.alpha.aussiehq.net.au";
$user="user";
$password="password";

mssql_connect($host,$user,$password) or die ("could not connect to
server"); // <-------- It always dies here. :(

mssql_select_db("trtrades") or die ("could not connect to DB");

....


?>

in php.ini file i set

mssql.allow_persistent = On
mssql.max_persistent = -1
mssql.max_links = -1
mssql.min_error_severity = 10
mssql.min_message_severity = 10
mssql.compatability_mode = On
;mssql.connect_timeout = 5
;mssql.timeout = 60
;mssql.textlimit = 4096
;mssql.textsize = 4096
;mssql.batchsize = 0
;mssql.datetimeconvert = On
mssql.secure_connection = Off
mssql.max_procs = 25

I know that the $host, $user, and $password are right because I can
connect to the remote DB with the client tools.

Please help me.

It looks OK, although which ntwdblib.dll do you have?
version 2000.2.8.0 does not work on server 2005.
You need version 2000.80.194.0.

Maybe it is your DNS, try the ip address rather than domain name 123.45.678.90
