Thx Felipe, after a week debugging, i found the problem!!

there was a mix up with SID's. i had 5 machines and username with the 
same SID
including the PDC.

but there is something funny were i need some help with,

if i make a new user or machine account, samba generate the SID 
i saw, that my server doesn't look at existing SID's.

how can i let samba make SID's after a specified number ??
my problem at the moment is that  if i make a new user, samba generate 
an existing SID, and there for
trouble arise!

example: current last SID in user database:  
if i make a new user samba will use: 
S-1-5-21-1968991162-2130249723-1959552931-5410    ????????????

so basically it's all about the last 4 digits!
can i alter a .tdb file ??? (if so witch one??)

all i like is samba to start making SID's after that -5462 number !!!

Cheers, Collen....
