Drive with DFS root low on free space - cannot find what is taking up the space

The C: drive on a file server (has a DFS root on it), has low disk space.  I cannot see what is taking up the space, and I was wondering if the DFS root is reporting some kind of disk usage somehow.  Has anyone seen this?  It is a 148GB drive with only 1.4GB left.  When I run a "TreeSize" on it, only around 6.1GB comes back.  An error saying that it cannot reach the network share for the DFS root does happen, but when I look at the properties of the share, there is no disk space usage reported.

Thanks,
Jose

It almost sounds like you have Volume Shadow Services setup on that volume and it's comsuming most of your drive.

You can check to see what VSS is using like so:

vssadmin list shadows

Let us know.

Here is the output of:  vssadmin list shadows.  I know that I don't have VSS set up on the C:\ volume, but what is "\\?\GLOBALROOT\...",  and where is that located?  And if that is what I think it is, how do I change it?
Thanks!

OK, let's see how much space it's using:

vssadmin list shadowstorage

Ok, so it's not on the C drive.

Sometimes Malware can misreport drive space.  You may want to see if you're somehow infected with something.

Can you also check what free space there is from a CMD prompt?

So this turned out to be a Symantec BackupExec issue.  The AOFO was stuck, and needed a reboot of the server.  The cached file went away after that.  No solution here, but thanks for your time.
