That's probably because the file is exclusively locked, and the "stat" performed by "ls" fails.

See if you see the file if you pass in the "-f" option to ls:

$ ls -f tsdiscon.exe tsecimp.exe

If you can, then this is the issue. Looks like CMD.EXE is able to examine whatever it needs from such files, but stat() in the cygwin library cannot (uses different APIs).

I see similar behavior in a file that PointSec drops in my C:\\ (PROT_INS.SYS). In fact, even "ls -f" is not able to get any info on that file!

% cmd /c dir /AH c:\\prot_ins.sys
 Volume in drive C has no label.

Nope, that's not quite it for me. I try "ls -f" but still don't see the file.

One interesting tidbit is that if, from the bash shell, I invoke
a Windows CMD shell, then that CMD shell similarly doesn't see the

I conclude from this that somehow the bash shell doesn't have
some appropriate privilege and that bash's children similarly
lack this privilege, but I can't figure out why two files with
seemingly similar permissions are different.

I note that I see this problem on a Windows 2003 Compute Cluster Server
domain controller head node (and its compute nodes) but not
not on a Windows XP 64 laptop.  (Perhaps something with domain
controller security policy is affecting this...)

Any tips on what other info I can look for would help.
