The post here is very useful, but still not able to solve my problem.
I have two system, one is Windows XP Pro, I can connect to SQL SERVER 2005 express without any problem (using the "localhost"). I am use the PHP from the Apache2 (XAMPP).
But when I try it on Windows 2003 server, it failed for all the possible combination, here it is what I did.
1. changed the ntwdblib.dll to the old version
2. try the secure_connection, on or off
3. try to use "localhost", "localhost\sqlexpress", "localhost,1533", "207.0.0.1", "207.0.0.1\sqlexpress". None of them work for me.
Actually, I like to know how to find the exactly error message for mssql_connection, then it may be easy to debug the error.
Any suggestion. Thanks.
