mount my own windows directory on a file server to my FC6 linuxcomputer

I want to mount my own windows directory on a server to my FC6 linux
computer.

My own windows directory on a server displayed in the windows explorer
is like this:
powah on 'server1file001\users' (U: )

server1file001 IP address is 172.20.10.30.
Mounting //172.20.10.30/Users is ok.
# mount.cifs //172.20.10.30/Users /home/powah/server1file001 -o
username=DOMAIN1/powah,password=zaqwoJ13!

# ls -ld /home/powah/server1file001/powah
drwxrwxrwx 1 root root 0 Dec 9 14:21 /home/powah/server1file001/powah

# umount /home/powah/ott1file001

Mounting //172.20.10.30/Users/powah fails.
How to mount //172.20.10.30/Users/powah?

# mount.cifs //172.20.10.30/Users/powah /home/powah/server1file001 -o
username=DOMAIN1/powah,password=zaqwoJ13!
retrying with upper case share name
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
