And yes, i agree also on this. 
If a re-join is done, it should prompt us and it could easily detect the secret files and remove them.
Or it should detect the currect secret files and then prompt for a re-join

Or even better, detect the secrect files, extract the "hostname" name from it, compair it with the current, then ask if its a rejoin or re-name/re-install of the os/samba.
If its a rename/re-install, is should remove the older DNS and AD records also. 
That could save some messages on the samba list i think.


Greetz, 

Louis
