Exchange server 2003 takes lot of disk space

Hi all,
I have a very serious problem in exchange server 2003 enterprise edition. I have exchange server installed in the D: Drive. the total no. of users are only 25 and no one has crossed more than 500MB. i have noticed that total D: drive (full exchange log files, database) altogether ha not exceeded 6GB. My total hard disk space is 50GB, in this exchange should have occupied only 8-10GB maximum. but presently the remaining disk space is 13.9GB? i don't know where the disk spaces are going on? can some one clarify and assist me. as this is very urgent and serious issue. 2 days before the remaining space was 15.5 gb and as on today it is 13.9GB, hope if i leave it for another 10-15 days, my hard disk will be empty. more specificially, exchange db is 5.2GB and log files are 4MB and no shadow copies. symantec antivirus server is running in this exch server. Ironport mail security appliance takes care for mail security (spam, virus...). can some one clarify me, where the space will be going out and how to solve this? any one ever come across

Check your backup if its purging log files or not once the backup is completed.
if you are taking a full backup/incremental backup it should purge your logs everyday. your logs directory should contain only the current days log files not the old log files.

Also search in the D Drive, for any big files of giga bytes. We had same problem some time back
there was a big file 17gigs , 18gigs was getting created every time we restart the systems.
Later we found that it was because of program( it collects the system configuration) which is trying to access system configuration and it could not access and it creates big temparory file of 17 gigs . we have disabled the program and rectified this issue.

Get hold of a tool called Treesize from Jam Software and run it on the server. See what it taking up the space. At this time don't delete anything unless you know what it is.

Actually, I recommend using DIRUSE on the command line - TreeSize cannot read and include files you don't have access to, and in most cases, that includes the contents of SYSVOL which CAN be huge.

DIRUSE, a microsoft command line utility, does not have this issue.
Scroll down the list of utils and download from here:
(it's under Directory Disk Usage)

Dear All,
Thanks for your immediate response. The problem is sorted out, as we know the microsoft technology, "Restarting" restarting the server, sorted out the problem. now 41GB disk space is free.

once again, thanks for all of your responses. good day. i am hereby closing my question.
