Cannot connect to SQL SERVER 2000

I am using php 5.3.1 to connect to my SQL SERVER 2000 on remote machine. I use Windows XP.
On using simple program like this:

$conn = mssql_connect("VBNET","sa","anythinghere") or die ( 'Can not connect to server' );

I get following error:

Warning: mssql_connect() [function.mssql-connect]: message: Login failed for user ‘sa’. Reason: Not associated with a trusted SQL Server connection. (severity 14) in C:\wamp\www\Mssql\test.php on line 8

Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: VBNET in C:\wamp\www\Mssql\test.php on line 8
Can not connect to server

I enabled TCP/IP and named pipes in my SQL SERVER and restarted it. Also its Authentication is set to Mixed Mode Authentication. So what am I missing here ?

Thanks in advance.

EDIT This question was first about SQL SERVER 2008 but later it was brought to my knowledge that it was SQL SERVER 2000. Forgive me for my ignorance but the problem still exists. So please give me suggestions.

Answer 1

This problem occurs when the SQL Serversecurity authentication is set
to Windows only, and one of the following conditions is true:

• You are trying to connect to a SQL Server database with a SQL Server login.
• You are trying to connect to a SQL Server 2000 Desktop Engine (also known as MSDE 2000) database that is installed on a Microsoft Windows
  98-based computer by using a trusted SQL Server connection.
• You are trying to connect to a SQL Server database from a Windows account that does not have sufficient permissions to connect to the
  server.

To work around this problem, use one of the following methods depending on the symptom that you are experiencing:

– A SQL Server login

Use a valid Windows login to connect to SQL Server. If you must
continue to use a SQL Server login, you can change the security
authentication mode in SQL Server to SQL Server and Windows. To do
this, follow these steps:

1. Start Enterprise Manager.
2. Expand Microsoft SQL Servers, and then expand SQL Server Group.
3. Right-click the server that you want to change to SQL Server and
   Windows authentication, and then click Properties.
4. In the SQL Server Properties dialog box, click the Security tab,
   click SQL Server and Windows, and then click OK.
5. When you are prompted to re-start the SQL Server service, click Yes.

– A Windows account with insufficient permissions

To work around this problem, you must add the Windows account to SQL
Server, and then grant the appropriate permissions to each database
that the user requires access to. To do this in SQL Server 2000,
follow these steps:

1. Start Enterprise Manager.
2. Expand Microsoft SQL Server, and then expand SQL Server Group.
3. Expand your server, and then expand Security.
4. Right-click Logins, and then click New Login.
5. In the SQL Server Login Properties dialog box, enter the Windows
   account name in the Name box. In the Domain list, select the domain
   that the Windows account is a member of.
6. Click the Database Access tab, set the appropriate permissions for
   the client, and then click OK.
