I know this doesn't apply in Chris's case, since he's already set up 
with domain security (as a domain controller), but I just wanted to warn 
everyone reading this who might be contemplating an upgrade to make sure 
your server is in domain mode BEFORE migrating from smbpasswd to 
tdbdsam. (I do not know the implications of migrating from server A in 
tdbsam to server B in tdbsam.) Otherwise, you might end up with some 
verrrrrrry strange browsing and authentication problems. I know I sure 
did. :-)

The problems are a product of the "user logon domain" being set to the 
server's NetBIOS name instead of the domain's NetBIOS name in tdbsam.

Of course, that can be fixed by migrating from tdbsam to smbpasswd then 
back, following the above example. Many thanks to JHT for pointing this 
simple fix out to me.
