HELP! PHP 4.4.4 and MySQL 4.1 - Can't find php_mysql.dll

I'm using Windows 2003, IIS and PHP 4.4.4 with MySQL 4.1. I had this
same setup on a server that got corrupted by a virus. I can't use any
of the files from the old setup so I'm trying to reinstall the same
versions. However, I can't find a php_mysql.dll file that will work.
All of the zip packages I download from php.net don't have the
php_mysql.dll file in the extensions folder. They have everything else
but that. Am I missing something? Please help if you have any idea.
The one php_mysql.dll file I did find and dropped in gives me the
following error:

Unable to initialize module Module compiled with module API=20050922,
debug=0, thread-safety=1 PHP compiled with module API=20020429,
debug=0, thread-safety=1 These options need to match in Unknown on
line 0

I'm guessing that means that PHP was compiled older than the
php_mysql.dll and that the dll is too new. Does someone have the older
version? Thanks in advance for the help!
