Attempting to use smbmount to mount my windows home directory fails:

(as root)
mount -t smbfs -o username=aclrk //homedir-server/A/aclrk /home/aclrk/windows-home
Password:
23129: tree connect failed: ERRDOS - ERRnosuchshare (You specified an invalid
share name)
SMB connection failed

This sharename exists;  it's the exact same share I mount on my windows xp box.
 It also appears if I use smbclient (although I cannot get smbclient to go
directly, it will only go to the top level share)

Here verbose output:
