please take a look at http://ez.no/products/ez_publish/info/requirements_for_ez_publish At first I would recommend to use apache and not IIS if you can.
To execute your cronjobs you can copy the php4ts.dll to c:\windows\system32 so It's found by the php client. Then create a small batch file like this:
@ech off
cd d:\www\mysite
c:\php4\cli\php.exe runcronjobs.php >> result.txt
Then create a sceduled task which executes the batch file.
