I have an Exchange 2003 server on a Windows 2003 OS. Drive is parititioned into C (operating system) and D (exchange mdbdata dirs). Did an offline repair with eseutil this weekend and although it may be just a coincidence, something is writing to my C partition and filling it up so quickly I can't keep up. D partition is behaving perfectly. II've repointed the event logs with regedit, but have to reboot to establish the change. I'm afraid to reboot with little to no space in case it doesn't come back up. What to do? Shadow copy is not on. No logs that I can find are on C. Ideas? Thanks!!
