Mr. Terpstra gave me a bit of help.  I had done nothing to set my
domainsid, but after doing the following:

net getlocalsid
net getdomainsid

The values are the same on both the old and the new samba server.  This
new server will take the place of my old one.  Right now it is on a
network with nothing else on it besides one of my old windows clients.  If
I remove one of my old clients from the domain and then re-add it, then it
logs in just fine.  If I take an old client from my current network and
put it on this new network and try to login to the new samba server then
it gives me the typical:

"Windows cannot connect to the domain either because the domain controller
is down or otherwise unavailable, or because your computer account was not
found. Please try again later. If this message continues to appear contact
your System Administrator for assistance."

The name of the Windows machine is business18 so I did an 'smbldap-adduser
-w business18$' to make sure the machine account was added in to the
directory, but the error was the same.  I even changed the uid of the
machine account to match the old one in case that was coming into play.

Here is my samba config in case someone sees something that I don't. 
Which is quite possible since I forget more than I learn it seems. :) 
I'll be reading on the How-To to see if I can pick anything else up.

Question: Because it reverses the logical flow of conversation.
Answer: Why is putting a reply at the top of the message frowned upon?
