samba - May 2007 - tree connect failed: Call returned zero bytes (EOF)

I am having trouble getting samba 3.0.24 to work with FC6. I currently 
have Samba 3.0.10 running on SL4.4 with no problems
if I check the smb service both smbd and nmbd are running but when I try 
smbclient -L localhost -U% I get the following:

Domain=[EARTHTEST] OS=[Unix] Server=[Samba 3.0.24-4.fc6]
tree connect failed: Call returned zero bytes (EOF).

Most google searches have not turned up anything helpful.

Most (removed shares) of my smb.conf settings are below.
[global]
   workgroup = EARTHTEST
   server string = Samba Server
   security = user
   hosts allow = 192.168.2. 134.117.32. 127.
   load printers = yes
cups options = raw
   log file = /var/log/samba/%m.log
interfaces = 192.168.2.169/24 134.117.32.169/24
   os level = 65
   domain master = yes
   preferred master = yes
   domain logons = yes
   wins support = yes

Poor planning on your part does not constitute an emergency on mine...
