[Samba] Samba will not start

[Ivan Ordonez]

Hi,

Right after I run "vampire" (net rpc vampire -S gia42c-1 -U Administrator) 
command, samba would no longer start.

The samba server was installed on Gentoo linux and running behind a 
firewall.  The PDC which is Windows NT 4 server is on different subnet with 
no firewall.  Please check the log and smb.conf below and see if there's 
anything I can do to make "samba" start again.

Thanks in advance for all the help.
