installing PHP GD library on IIS

hi all,

i have a big problem!

t'm trying to install php_gd.dll extension to my PHP 4.06 on IIS 5.0 and when I change entries in php.ini like

extension_dir = c:\php\ext\
extension=php_gd.dll

and try a test code i encounter

Fatal error: Call to undefined function: imagecreate() in c:\inetpub\wwwroot\test2.php on line 7
PHP Warning: Unable to load dynamic library 'c:\php\ext\php_gd.dll' - The specified procedure could not be found. in Unknown on line 0

what is happening??!? i ran out of ideas....

TIA,
boris

...seems like i'm missing libsasl.dll

if smbdy has it on machine, i'd appriciate attaching it in post, i can't find it on the web...

thx
