I just wanted to post another update.
it has now been weeks since deployment.
I checked number of fragments and looked at the file types:
the first 2 users I looked at?
Tiana 37% and 4,854 fragmented files
Lisa 41% and 3,452 files
When I look at the files there were a lot of them that were left overs from the initial deployment windows update (silverlight install files, other installer related files, etc) and general use files (outlook.ost, office program files, etc).
What do I take from this? its been pretty much doing just about nothing. My solution would not be to run ccleaner or similar because that would only mask the fact that there are many fragmented files, all of which defraggler has not defragmented. This is not limited to a specific directory.
My scheduled task is also set to retry for 400 minutes. I can confirm the task is launching and I do see df running in the background. The users are also local admin if that helps.
Unless someone else can think of a reason for this to be doing prettymuch absolutely nothing I will probably be looking at ultradefrag next or similar to find what I need.
It's too bad defraggler does not have a good idle time defragmentation scheme for automated maintenance built in.
