Windows Server SBS 2003 - low disk space

I'm having this pretty weird problem. Our Dell, factory installed, SBS 2003 installation keeps running incredibly low on disk space on the system partition. The hard drive installed in the server is a 500GB, but Dell only partitions the C Drive with 25GB of space. I've moved all the Exchange 2003 data to the D partition as well as user files and such, so there shouldn't be any great increase in data over time.

Regardless, every 2-3 days the server requires a restart. It will run through 5-6GB per 2-3 days for apparently no reason. As soon as the server is restarted all that space is magically back and available to the system again. Another 2-3 days pass and the server runs out of space and the cycle starts again.

I've run disk cleanup (shows nothing worth deleting/removing). I've run TreeSize Free edition, which shows which folders are taking up the most data and nothing at all seems out of place. The really weird thing is that it only shows around 10GB (out of 25GB) used regardless of whether the server has run out of space or whether it has 6GB free after a restart.

Not sure where else to look. I notice that TreeSize does not report the size of the system volume information folder on the C drive (due to access denied). Is it possible this folder is eating up the space on the C drive and then releasing it after a restart?

It's sounds like you have the same problem I had when I started my current job.

The issue is the paging file, you need to move it to another drive.

This can be done by right clicking on 'My Computer',
Then choose 'Properties',
Then choose the 'Advanced' tab,
Then choose 'Settings' under the Performance Section,
Once again choose the 'Advanced' tab in the new window that shows up,
The select 'Change' at the bottom.

You will now see the Page File Options, you need to select the C: Drive (assuming thats your system drive with the OS installed) and choose 'No Paging File' and then click 'set'.
Then select a different drive with a custom size of what you had before written down.
Click 'set' and 'OK', it may require a reboot of your server.

Hope that helps, come back if my instructions don't work, or the solution doesn't as I have another option, 2 problems were what caused my issues but this was the largest issue by far.

It's a common problem for us too.  
I agree with tomuky2k.  Additional places to look are:
c:\program files\exchsrvr\mailroot\vsi1\badmail - can be very large if you get hit by junk
Also switch off shadow copy on C drive - this uses up space which you can't see.
Move any Dell installation files to D drive

I'd second Tomuk72k and say your paging file is taking up space. How much ram do you have? Did you go for a maximum (4GB)?

The paging file is relative to the amount of Ram you have installed.

I don't think it is a paging file issue. I could try turning it off, but the RAM usage has never gone beyond 2GB (we have 2GB installed). That being said, it is set to grow up to 4GB, but hasn't moved past the approximate 2GB starting size.

There are no files in the badmail directory.

Any other ideas?

I just turned off hibernation support to free up another 2GB and 10 minutes later I'm already down another 100-150MB.

If it is not the page file, download and install a trial of Treesize. Run a report now (after restarting the server) and then run again when the server fills up.

The report it generates will show you exactly where the data has grown and you can compare it with the orignal report. This will narrow down what is stealing all the space. From here you can examine more.

I totally missed the bit that you have run treesize already.
I'm a bit lost also. You could try this (http://www.petri.co.il/forums/showthread.php?t=7183) but I'm clutching at straws

Have you tried clearing the space by using the disk cleanup wizard? Do you get anywhere?

I would move the paging file anyway if you can.

Disk Cleanup Wizard shows next to no space available to recover.

I have a feeling it is in fact the indexing service. For some reason it's enabled...I will disable and give the server a restart later tonight to see if this fixes the problem.

I'm having the same issue.  I got a lot of space back by deleting some old shadow copies.  Right click drive > properties > shadow copie tab.

But the free disk space is still far lower than expected.  Did you ever find a solution to this?

It was the indexing service. For some reason it was enabled and it was making the system volume information HUGE between restarts.

I have just solved this problem again. Do you have any Sage products installed or hosted on the server?

stevew1999Commented:
Interesting question.  I have ACT! running.

What did you find with sage products?

Sage Line 50 Accounts, Manufacturing and HR all store the databases on the C Drive by default. These can be moved, I'm not sure about how to move the Accounts and HR as we upgraded to Sage 200 which is a sql database which is easy to move. Hence Line 50 Manufacturing which is a sql database and can be moved easily in the SQL Server Enterprise Manager.
