No, the "-n" option to ls forces it to output numeric values instead.

That's the default mode Windows gives it.  This should work, but somehow
doesn't...  Can sshd get to all the necessary files and directories?  Look
at the permissions on /etc and the files in it, as well as /bin.

Ok, looks like all your mounts are system mounts, unless you simply don't
have the permission to read the registry keys for the SYSTEM user...

Hmm, try looking for wrong directory permissions, that's my only guess at
this point...  Sorry.
