How to connect to Microsoft Sql Server 2005 with PHP

[eluser]FutureKing[/eluser]
I am trying to connect to MS SQL Server 2005 with PHP using following code:

Code:

mssql_connect('SQL5.ZNETINDIA.NET','user','pass') or die(mssql_get_last_message());

BUT IT does not work.
I also tried to connect to my local sql server 2005 developer edition database But it also did not work.

Code:

mssql_connect('ANKURGUPTA-PC\SQLSERVER','user','pass') or die(mssql_get_last_message());

I get following error:

Code:

Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: SQL5.ZNETINDIA.NET in G:\websites\project.localhost\mssql.php on line 3

In the above code only username and password has been changed. Actual user name and password is not "user" and "pass".

I am 101% sure about my database server name, its username and password.

Is there any problem in my PHP configuration? I am using WAMP Server with php_mssql extension enabled.
