Ok, I did some research and got this to work. For people who don't know how to set up a cronjob in Windows/IIS, here is how I did it.
First I created a .bat file called cron.bat, created it in notepad and saved it as that file name, here is the code:
SET PATH="c:\PHP"
start php.exe timemail.php
timemail.php is the file I wanted to run. C:\PHP is the location of my php.exe file that will run it. The only way I could get it to work was by putting it in my web root. I don't know if this is a security problem or not, but i'm running this on my network intranet server so I can get away with it. I then set up a schedule to run the cron.bat file at a specified time. my timemail.php file pulls data from my calendar and sends an email to designated people stating what events are occurring for that day, i let it run at like 4am before everyone gets to work. Thats it. I thought this was going to be real hard, but it was quite easy. Fearing the unknown is no fun.
Thanks for ya'lls help with getting this running, I really appreaciate it.
