[Samba] tree connect failed: NT_STATUS_BAD_NETWORK_NAME

[Charlie McElfresh]

Hi,

I am running samba 2.2.12 on Freebsd 4.3, on an
internal network, with no firewall.  I have a very
simple smb.conf.  Here are the relevant entries:

[global]
   workgroup = Workgroup
   socket options = TCP_NODELAY
   printing = bsd
   guest account = nobody
   hosts allow = 192.168.1.0/24

 [tmp]
   comment = Temporary file space
   browseable = yes
   writeable = yes
   path = /temp
   read only = no
   public = yes
   create mode = 0777

/temp is owned by nobody, and has read / write
privileges for everyone.

My windows machines can see the samba server, but they
cannot browse to it.

When I run 

root at machinename# smbclient //machinename/

I get the following output:

added interface ip=192.168.1.151 bcast=192.168.1.255
nmask=255.255.255.0
Password:

Help appreciated.
