My question is a little more detailed, though.  I have heard some folks 
claim that once the client logs on to the domain there is no need to log 
on to individual domain member servers.

>From the user's perspective that may be true, but I believe it is because
the client caches the credentials.  I believe that, upon connecting to a
new SMB server (a domain member server), the client must still go through
the SMB logon process, and the SMB server still performs the
\\PIPE\NETLOGON authentication step.

That's what I got from re-reading the documentation that's available after 
I posted last night.

I've read a few things which state that NT Domains pass "tokens" that 
allow the client to authenticate with servers without having to re-submit 
credentials (even cached credentials).  That model applies to Kerberos 
authentication, certainly, but I don't have any evidence that anything 
like that is outside of Kerberos.

Thanks for the reply!
