server cleaner

I am using and recommending CCleaner to everyone that I know...I use it regularly on my PC at work and home.

I am trying to find the best way to schedule a cleaning of those little annoying places on our windows 2000/2003 servers that build up, IIS logs/ bad mail folder ect...

I am wondering how well CCleaner works on windows servers and if there are any problems that anybody has run into with using CCleaner on servers and as a scheduled task.

Any experiences shared are greatly appreciated.
