Default ACL: Users can create folders & files ..?

[steve]

Hi,

On my new windows server 2003 R2 SP2 boxes, I spy that the default ACL on
all drives is that Users have special permissions like so:

Create Folders / Append Data : This folder and subfolders
Create Files / Write Data : Subfolders only

Is this correct? Can I safely remove these special permissions?

Thanks
steve
