I am slowly running out of space on primary drive (c:) on exchange server box. It is Exchange 2003 on WS 2003 and is a DC. I had almost 2 GB free at one point, but it is now down to 700mb and falling. The MDBdata folder is on anther drive as are the log files (E0____.log). The only thing that I can tell that is taking up any space are the IMF archives, but that is less than 100MBs at any given time. The only other programs on it besides Exchange are IIS 6, Sophos PureMessage, Diskeeper 8 Server, and Acronis True Image Server 9.1.
How do I clear up some space without messing up anything?
