Backup of PC share using smbtar

[Dennis Puk]

I'm trying to do a backup of my Windows 2000 PC share thru the smbtar.
However, I get this problem:

samba at sunA:~[516]$ smbtar -v -s dpuk -t backup.out -x "backup"
server    is dpuk
share     is backup\
tar args  is
tape      is backup.out
blocksize is
added interface ip=137.132.87.10 bcast=137.132.87.255 nmask=255.255.255.0
Got a positive name query response from 137.132.1.63 ( 137.132.90.155 )
Anonymous login successful
Domain=[COMPUTING] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager]
tree connect failed: ERRDOS - ERRnoaccess (Access denied.)

What does this mean? I've already set the appropriate permissions on my PC
share but I still get this access denied message. Thanks.
