I'm seeing an "Permission denied" failure when using chmod on a mapped netw=
ork drive.  The problem doesn't occur on the local drive and if I use a Win=
dows-style backslash in the name, it works?!

CYGWIN_NT-5.1 EHOLMBER-XP 1.7.1(0.218/5/3) 2009-12-07 11:48 i686 Cygwin

$ echo $CYGWIN
nontsec

eholmber AT EHOLMBER-XP /cygdrive/b
$ touch test.txt

$ ls -l test.txt
-rwx------+ 1 eholmber Domain Users 0 2010-02-26 11:16 test.txt

$ ls -l .\\test.txt
-rw-r--r-- 1 eholmber Domain Users 0 2010-02-26 11:16 .\test.txt

$ chmod +w test.txt
chmod: changing permissions of `test.txt': Permission denied

$ chmod +w .\\test.txt

$ ls -l .\\test.txt
-rw-r--r-- 1 eholmber Domain Users 0 2010-02-26 11:16 .\test.txt


Any help is greatly appreciated!

Thanks,
Eric
