Using du.exe to calculate disk usage on a Microsoft cluster server

The problem is still here.

As a refresher, here's the original problem:
===========================
I need to determine disk usage for each directory on a Microsoft cluster 
server. As a linux junkie, du is *the* tool for automating this kind of 
stuff so I installed cygwin, mapped some drives and tried to schedule 
the utility to run at night. However, I get a lot of errors thrown back 
such as:
1. "No such file or directory" - Which tends to appear on weird 
filenames (like with spaces or ' or some other character) or when I 
don't have permission to access the drive (but that's something I can fix)
2. "File name too long" - Which it is, but I'd hope there is some way to 
get around this
3. "du: fts_read failed: Permission denied" - That's the last error 
message I get. The program seems to crash at this point.

I've seen no such issue in Linux and Google responses to the third error 
are rare and unhelpful.

My question to the list is:
1. Is there a way to eliminate the errors above (especially the third so 
it can at least complete)
2. Has anyone else found a solution which will properly report the 
amount of disk space a particular directory is occupying? Something that 
is free and can be scheduled to run at night.
=========================
I actually do not think the problem is escaping characters or spaces. 
There are other files and directories which can use spaces no problem. 
It must be actual permission problems which I can fix.

The command I am running is:
du -sh /cygdrive/s/*
This is because I want to know the size of the first level directories 
under the S drive. I will try
du -sh /cygdrive/s
to see if I get the same errors, but that will not fulfill my requirements.

Can anyone tell me under what circumstance the message
du: fts_read failed: Permission denied
would come up. I should be able to troubleshoot things from there if 
only I knew what that error message is really complaining about.
