Should I remove the old versions (not used here) of ntwdblib.dll?

Answer 1

The flavor of the Microsoft SQL Server Driver for PHP that you enabled in the php.ini file is the Thread Safe VC6 version. Therefore, you’ll need to install the appropriate version of PHP run-time (i.e. VC6 x86 Thread Safe) from http://windows.php.net/download/.
When installing PHP, you should select the IIS/FastCGI option, and then establish a mapping between IIS and php-cgi.exe. In other words, your IIS configuration should point to the PHP CGI executable and not php5.dll that happens to be the Non Thread-Safe PHP run-time.
Moreover, the library ntwdblib.dll is not needed anymore.
On final note: it might be worth upgrading your IIS to at least version 6.0 that was optimized for FastCGI usage.
Hope this helps,
