sam_logon is used for domain logons.  I don't remember 
if it is part of the joining process.  What you need to do
is to 

	o set the debug level to 10 in on smbd
	o set log file = /tmp/log.%m
	o set debug timestamps = no
	o join an NT4 client to the domain
	o grep the log file for 'api_rpcTNP'

MSRPC is Microsoft's version of dce/rpc.  It works like this

	   MSRPC
	-----------
	named pipes
	-----------
	    SMB
	-----------
	  NetBIOS
	-----------
	  TCP/IP

Not very pretty huh?  The SMBsessetup&X call is used to 
establish an SMB session in user mode security.  The process 
is as follows

	1.	negotiate and SMB protocol dialect to use
		(SMBnegprot)
	2.	authenticate the user
		(SMBsessetup&X)
	3.	connect to a share (IP$)
		(SMBtcon&X)

All of these are request / reply pairs.

Once you have a connection to the IPC$ share, the client 
can setup an named pipe such as \samr, \spoolss, \srvsvc,
etc... and then begin to issues RPC operations.

It is the RPC ops which implement the domain control protocol
(which is very messy).
