I have a windows server 2003 system which for some reason is loosing disk space at the rate of roughly 300 Mb per day.. I have run the utility Win Dir Stat against the drive which is loosing space and it is showing there is 5.1 Gb of space on the drive but this utility is showing it as unknown.. Any ideas would be greatly appreciated as i really need to reclaim this space..

What do you mean  
it is showing there is 5.1 Gb of space on the drive but this utility is showing it as unknown.

Is it some specific folder that is shown as unknown size?

If so try to delete from CMD "del PATH /f /s /q"

Actually windows doesnt see the space at all, it is only showing 1.2 Gb available , however the utility shows there is 5.1 Gb available but is shows it as unknown.
Do you have any applications running on the server

What is the function of this server?   That will help narrow it down, for example if it runs any web services you could check IIS logs, file server you could check shadow copies, etc.

This server is used as an exchange server
Have you cleared the logs

I'm not an exchange guru I'm afraid

do you have any other applications or services running on it?

Backing up with an Exchange aware backup program should delete unused transaction logs.

Would a transaction log file show up as unknown in Win Dir Stat? Its almost like its has this space is being use by an unknown file system or something?

No, windirstat should be able to see the log files so they're hidden from it, probably restore points in sysvol - http://blog.windirstat.info/20061013/unknown-space/

Maybe run a checkdisk?
just a guess...

Maybe an error in MFT ..
