php_gd.dll problems

Please can someone help out here?Been trying for the last two hours to get my server load php_gd.dll with very little results.I have uncommented my php.ini(4.3.1 win32) and variously located the dll file in my top level php directory and in winnt/system32 with the server telling me each time:
Unknown():Unable to load dynamic library './php_gd.dll' - The specified procedure could not be found.

Please can any one tell me where I am fouling up?

hey obi,
did you check the extension directory setup in your php.ini file? by default its just "extensions" in your php folder, so you might want to check that out first...

Thanks mytch for the help, but the php installation didnt come with an extensions directory.Instead I transferred one from my installation file(the original unzip) and placed it inside the C:/php still with the same effects.thanks for the help though

Thanks Mytch, finally got it right this time.Think I was putting too much faith in the installer.It leaves the extensions directory behind in the download files and in php.ini the you are asked only to uncomment as if their is in built action pointing you to the requisite directory whereas you have to go the extra step and reference it thus
extension=extensions/php_gd.dll

Thanks again for the pointers
