Need Help Installing ImageMagick on Windows IIS 6.0 with PHP

Can someone help me install ImageMagic on a Windows 2003 Small Business
Server running PHP 5.2.5 and IIS 6.0? This has been driving me crazy all
day.

I have downloaded php_imagick.dll from the php4win.pecl.php.net site and
copied it to my standard extentions directory. I have successfully installed
the static 8-bit version of ImageMagick from their site. (ImageMagick works
fine from the command line.) I have also added an extension=php_imagick.dll
line to my php.ini file and restarted IIS services. No matter what I do,
when IIS restarts I get a message saying that it is unable to load the
extension. Any ideas? I have searched the Web for a solution, but to no
avail. Thanks!
