Good night friends !! I made a mess and need help heheheh put a Samba 4 as a member of cmc.corp domain with the command: samba-tool domain join cmc.corp DC -U Administrator --realm = cmc.corp Performing tests with the samba versions 4 I changed the /etc/default/Sernet-samba AD to CLASSIC and after that I lost the connection between them when they give a wbinfo -t I get an error message. I entered the windows 2k8 and typed dsa.msc and tried to remove this machine for him and it was not possible. Now comes the question how do I remove this machine without harming the current structure? Hugs and thank you all !!! Gabriel Franca
