[Samba] SMBTAR problem

[Andy]

Can someone look at my smbtar session below and tell me what is wrong?
I have Redhat 7.3 with Samba 2.2.5 installed from source.
I am trying to use smbtar to backup my NT server and am testing with a 225MB
share its going really slow on my 100Mbps network.
Also....Why does smbtar try to look at /etc/samba/smb.conf?
My smb.conf is at /usr/local/samba/lib/smb.conf.
Thanks for any comments on my problem.
