Hi It's been the second time it happen to me on to different site and server After a anormal shutdown (electricity failure) my ldap database get corrupted and I had to repair/restore it. So samba was running but can't access the database after this samba seem to work without any problem but all the people on xp station can't logon the domain anymore Windows XP say IT can' find the domain controler The only solution for the xp is to rejoin the domain again. no change at all on samba One site got 40 XP workstation so It take a while But I'm sure I'm missing something I've check the domain SID I've check the ldap password I've delete the cache rm -r /var/cache/samba/* but there is no way to make it work again without rejoining the domain so if someone can help me and explain me why it happen ? thank
