Disk spage agressively being chewed up by something

Hi Experts,
   I really hope you can help me out on this one cause I've been banging my head  on it all weekend. I have a windows 2003 server running Exchange 2003 e also have ISA server installed. Everything was fine until last Thursday when the server reported it had no more disk space available. That sounded strange so I removed some log files and some unused files freeing up about 8gig of data. The whole sytem went back to normal when all of a sudden I noticed the disk space going out rapidly at a rate of 1 gig per min. I thought someone was in our network so I disconnected the server isolating him still the space was being chewed up. I did a seach on modified files but nothing came up. Needless to say the server became really slow. Any Idea what this can be ? I checked the ttask manager and everything looked normal. We aslo have AVG installed and it did not detect any viruses on the system.

I'm doing a backup right now KCTS the store and site replication services using NT backup. Will transaction logs automatically clear after backup ?
Biju708Author Commented:
did that but it did not help at all I still have the same problem. Any other ideas ?
Biju708Author Commented:
What I noticed now is that after a restart everything works fine, then after about 10 minutes Outlook clients will not update their emails from the server this will then start the disk consumpion on the server. I am really at a loss here since I have never seen anything like it. any help will really be appreciated.

NOw I just cloned the drive and replaced it with a new one maybe it was a drive problem
Biju708Author Commented:
That did not do the trick either. I'm really at a loss now no idea what it could be.
Biju708Author Commented:
I am now checking the login logs and it seems that the server crashes evertime a particular user logs in via MAC entourage is it a possibility or that cannot be ?

Biju708Author Commented:
I think I found the solution here


I will test it out and see what happens.
