[Samba] Desynced DC

[L.P.H. van Belle]

On the failing DC. 

Stop samba 

Remove the content of 
/var/lib/samba/*.tdb
/var/lib/samba/private/* 
/var/lib/samba/sysvol/*
/var/cache/samba/* 

Remove the old DC from the AD domain. 
Remove the old DC from the dns domain.

Now you can join again. 


Greetz, 

Louis
