Has anyone successfully made samba work using the vboxnet virtual 
internal LAN of VirtualBox to allow a MS Win client to print to the 
Linux CUPS printer under SL 6?

If so, I greatly would appreciate a copy of your samba configuration file.

With my configuration file, I get errors such as:

Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.5.4-68.el6_0.2]
tree connect failed: NT_STATUS_LOGON_FAILURE

using smbclient from the linux side.  This failure also happens when I 
use 127.0.0.1 as the allowed IP address (ifconfig -a shows lo on this 
address), not just the IP of vboxnet0 that does not exist except when 
VirtualBox is running a guest OS.

Also, if you have had success, how did you setup the password file for 
samba in terms of encryption, password program, etc.?  I have attempted 
to use both swat and webmin, as well as manual editing, but still cannot 
get samba to work.  Note that I do NOT want samba on any external IP 
address, but only on an internal network.

I had gotten samba to work with VMWare a number of years ago, but my 
notes from that epoch are not solving the current problems.  For lack of 
licensing funding, I cannot run VMWare workstation at this time.
