    I'm running SBS 2003. I have a 20 GB system/boot partition @ C:\. Free
    space is showing as <800 MB. However, the sum of the disk space used based
    on enumeration of folders/files is 10.57 GB. This suggests there is a lot of
    phantom usage. I do see, looking at disk usage in the disk defrag utility
    tha almost all disk space is used and a lot of it, ~15-25 % is in unmovable
    files.

    Dose anyone have a clue about what's going on?

    Are you running Exchange on the SBS server? Try downloading TreeSize. It is
    a freeware program that will break down the folder structure and show
    exactly where the space is being used.

  3. Also - make sure you have set your folder view options to show hidden and
    system files. This can affect size calculations as well . . .

  4. And if your pagefile is on the C: partition, move it to another partition.
    If you have 2 GB of RAM in the server, your pagefile.sys is probably 3-4 GB.
    Another big user of space may be Volume Shadow Copies. And then there's the
    $NTuninstall file in the Windows folder. If necessary, these can be copied
    to another partition and then deleted from the Windows folder (but save them
    because you can't uninstall a security patch, hotfix or service pack without
    them).

    What are the $NTUninstall folders? Can they be deleted?

    Apart from what the others have said, you might look at the user
    profiles. If you don't have permission to see into them, you won't see
    them counted (or in TreeSize either), but they still subtract from free
    space.

    If the users don't have quotas, you'd be amazed how much space they can
    fill with personal stuff, and that's not counting the enormous caches
    that many applications create.
