Unable to run scheduled task, getting a HTTP 401.2 error

I have a scheduled task that I setup in the CF administrator. It calls a page which runs some queries and inserts some data into tables. I checked the output file, and I'm getting this error:

HTTP 401.2 - Unauthorized: Logon failed due to server configuration

I'm using Integrated Windows Authentication on my site because I'm using LDAP security within my application.

Does anyone know what I need to do so I can get this page scheduled? I'm assuming I need to mess with security, just not sure where to begin.

If you access the page directly, what login credentials do you need to provide?
