You can use Task Scheduler to schedule calls to a webpage url every mins/hours/daily/month or other schedule time.
Steps:
1. Create a Visual Basic script:
Call CallUrl()
Sub CallUrl()
On Error Resume Next
Dim objRequest
Dim URL
Set objRequest = CreateObject("Microsoft.XMLHTTP")
URL = "http://www.andrew.sin.com/index.pl?doScheduler=1"
objRequest.open "POST", URL , false
objRequest.Send
Set objRequest = Nothing
End Sub
2. Use Task Schedule to schedule call(s) to the vbs script, ie: run the vbs script at specified times.
