Tweaking my boot process

[Bill]

Hi,

This isn't a big problem but my boot process is a bit slow.  One thing 
that I noticed was that there were two successive starts of the 
SMB/CIFS  server.  I assume this is Samba.  The first call is OK but the 
boot process takes while for the second start, which is redundant.  What 
file do I have to edit to comment out the second call.  Also I would 
like to comment out the unnessary services such as the bluetooth server 
(I don't use any bluetooth devices ???) and the Virtualbox additions and 
anything related to VirtualBox.

The parts of the boot log I am talking about are as follows.  If the 
entire boot log is desired, I can provide it.

Starting bluetooth daemon  [ OK ]
...
VirtualBox Additions disabled, not in a Virtual Machine
...
Starting SMB/CIFS File and Active Directory Server  [ OK ]
Starting SMB/CIFS File and Active Directory Server  [fail]
