PhP 5.2.17 not detecting MSSQL 2000

I'm currently using IIS7.5 on Windows Server 2008 R2... I've got it setup to run PhP (5.2.17 AND 5.3), and at some point I had MySQL 5.5 too...

Now the thing is, I've changed the backend DB and altered the PhP codes to work with MSSQL 2000 (RTM), the 开发者_StackOverflowproblem is, IIS can establish a connection string to a particular DB inside the DB Server, but PhP doesn't wanna see the MSSQL server. There's no mention of it in the PhPinfo report...

I've done the basics, uncomment the required in PhP.ini, configured IIS to process PhP, etc.

But I can't get PhP to work with MSSQL 2000 for the love of me... Any ideas?

There's a small bit of code that needs to be uncommented in the PHP.ini file... I made a mistake by misconfiguring the file... When I did take the sweet time to reformat and reinstall everything, I realized that I had forgotten to uncomment the line which allows PHP to see the MSSQL driver...
