I'm trying to replace an old Windows 2000 server that is current set up with a 
number of open anonymous shares used by a legacy application that must remain 
in production for a few more years.  I spent a few hours trying to create 
anonymous shares on a 2008 R2 box but gave up.  My next idea was to use Samba 
to create an anonymous share, and following this quick-n-dirty HowTo: 
http://www.debuntu.org/samba-how-to-share-files-for-your-lan-without-userpassword/,
 I set up a Lucid Lynx box with samba (3.4.7~dfsg-1ubuntu3.10) to do just that.

Works great... as long as you're on the same subnet as the Samba server.

So our subnets are roughly set up thusly:

 * 172.21.11.0/24 - Linux servers
 * 172.21.110.0/24 - Test PCs (Win7 x64)
 * 172.18.224.0/20 - Production PCs (Win7 x64)
 * 204.133.165.0/24 (treated as an internal network, don't ask) - Old server 
subnet

And the specific machines I'll be discussing are:

 * 172.21.11.24 - Samba server (wrc-deploy)
 * 172.21.110.68 - My test PC (Win7 x64)
 * 204.133.165.24 - Old Windows 2000 server

So from another Linux server, on the same subnet (broadcast domain), I can do 
the following without a problem:

jheese@wrc-aptcache1:~$ smbclient -NL wrc-deploy

Great!

However, from my Windows test PC on the 172.21.110.0/24 subnet, if I try to 
browse to \\wrc-deploy or \\wrc-deploy\RMSDist, say, I get "The account is not 
authorized to log in from this station."

However, and I think this is key, I can browse to \\172.21.11.24 and 
\\172.21.11.24\RMSDist without a problem...  DNS is absolutely working 
properly, and I can ping, telnet, etc. to the name "wrc-deploy" from my test PC 
without a problem.

Also, I know that it's not the old NTLM/LM security options because I can hit 
the old Windows 2000 server's shares from my test PC without a problem, and 
it's on the old server subnet, 204.133.165.0/24.

To my knowledge, no WINS server has ever been configured on this network, nor 
do we have any broadcast forwarding configured on our routers to make the old 
server's shares browse properly.

I've Googled the crap out of this, including the specific error message, seeing 
about using Samba 4.x to do this instead of Samba 3.x, whether WINS is 
necessary (I'd really like to not have to go this route if possible), and 
everything else, but I can't find anyone else in this same situation.

So, can anyone please suggest ways to make this work.  I don't care how it's 
done, but the requirements are:

 * Anonymous CIFS shares
 * Works by name across subnets
 * Without a WINS server on each subnet (we have waaaaay too many subnets, some 
in weird places)
 * (Preferably) Without WINS altogether

Let me know if you need any specific information as far as config files, 
versions, or diagrams.  Thanks in advance!
