Active Directory installed on windows server 2003 and excahnge 2000 also installed
Exchange files are on D drive (135GB). Free space on D drive is showing 59GB and sometimes its showing 19GB keeps on coming down suddenly system restarts and it shows 59 or 58 GB agian.
Actual free space should be 95GB as the other is consumed by Exchange.

I don't have any monitoring tool, I have attached the Disktective report

I have run NTbackup for Exchange and System State Now my free space is 65.5GB .priv1.edb=17818.. priv=4556 .. pub1.edb=22536 ..pub1=106.504 and total log file size = 11.9GB. All this file size accounts for around 100GB approx. Apart from free disk space reduction problem where do you think is the other 35GB (Total drive size=135GB)

what is oobech.exe service ? It shows up randomly
