Getting GD2 to work on Windows 2000 SP4 (PHP 5.1.6)

I have tried everything.. GD will not enable! Essentially, I have

extension_dir="C:\PHP\ext"
extension=php_gd2.dll

I've added c:\php\ext and c:\php to my windows path variable. I copied php_gd2.dll to my system32 folder.. I've scanned my entire INI file to see if there was any other reference to the extension_dir, or GD2.dll extension line, and nothing... GD Still will not enable.

UPDATE

I changed the php.ini files in my C:\PHP folder as well as my C:\WINNT folders - actually they both show that GD should be enabled - I also upped the memory from 8M to 32M in both files and no luck, still.

UPDATE 2

We are moving the darn thing to a different server. It's not worth all of the time trying to get this darn thing working. Thanks to all that contributed.

I had this problem once upon a time. IIRC PHP was not using the php.INI file I thought it was using, so all my edits had no effect.

Oh! I even blogged about another difficulty I had with GD on Windows, after I convinced it to find the GD2 DLL in the first place. That was on Windows 2003 but I think it applies even more in 2000land.
