>Description:
 I read-only mount Windows C$ shares onto my NetBSD box to scan them for virus
infections.  An "ls" of the mount shows the typical "WINNT" directory, but if I cd into
that directory with another name, like "winnt" or "WinNt" or "Winnt" it seems to create
a new empty directory for me on the remote machine.  There are no errors.  When I
unmount the directory and access the C$ share with smbclient (from Samba) I can see
these new directories but I can't access them.

 If I try to cd to a totally bogus directory like "XXXXXXX" then I get the expected
"No such file or directory".  Likewise "mkdir RRRRRR" gives "Read-only file system".
"mkdir winnT" gives "File exists".

>How-To-Repeat:
mount -r -t smbfs -o -I=<IPaddress>,-W=<domain> //<userid>@<NetBIOSname>/C\$ /mnt
cd /mnt
cd WinNT
cd ..
cd Winnt
cd ..
cd WINNt
cd ..
ls
