My host has PHP compiled as an Apache module. I am hoping to run the cron.php file every 5 minutes. The file is just a test and sends me an email. That's all. Either I have specified the wrong path or my syntax is wrong because it is not working. MAILTO=myemailaddress.com */5 * * * *...

I wrote a vb.net 2008 program to upload a file to a web server. It works fine when executed manually, but has issues when scheduled on our Microsoft Small Business Server 2003. It works for about a week, then just stops working. On the web server, I get a zero-byte file. I think this...
