I have Small Business Server 2003 and I get the reports from it every morning at 6am. At 6am it says that there is around 14MB of free space. By the time I get to the server at has already cleared up and is at 3.5GB of free space. I have logged in early enough to see that it is in fact at 14MB but by the time I start looking at folders at somehow frees that space back up. How can I monitor this to find out what folder is growing in excess of 3GB everynight?
