Unable to load dynamic library

[trekmp]

Hi all,
I'm using PHP5 and MySQL 5 running on Windows Server 2003, the installation of both all went well, but when I try to run a website I keep getting the above error.

I know its to do with the php_mysql.dll and libmysql.dll, but I cannot sort out this problem, I'm fairly new to PHP.

The version of php_mysql.dll=5.0.2.2
Cannot find verion of libmysql.ddl but its 1,272KB in size

I've done what other sites have suggested.

1. Enabled the PATH variable to point to where php is ;d:\php;
2. In php.ini enable the extension_dir to be d:\php\ext, even tried d:/php/ext nothing
3. Enabled extension=php_mysql.dll
4. Copied php_mysql.dll into the above dir, still nothing
5. Copied libmysql.ddl into the above dir, still nothing
6. Copied both dll's into c:\windows\system32, still nothing
7. Copied them into c:\windows
8. Restarted server nothing

Its just keeps saying unable to load dunamic library d:\php\ext\php_mysql.dll, buts its all there, so what is wrong.

I've not tried completely uninstalling PHP and reinstalling it on the C drive and set IUSR to have full permission to that directory and still I get the error, what am I doing wrong, this is driving me nuts.
