Question : Can't write to C Drive on Windows server 2008

I'm using Windows server 2008.  
Folder is marked as READ-ONLY, so i've unchecked it and the subfolders.
I'm an local administrator on the box.

I can't edit a document, and save it to the same path... won't overwrite.
I'm able to save somewhere else, then copy / paste it OVER on the C drive .... but won't let me directly edit.

what gives?

No you can turn it off but that's about it.
In R2 you can adjust the sensitivity.
