Hello All, I have two question: some time ago, I performed a migration of a Samba 2.2.5 to Samba 2.2.7, and when I try to login into a client, I receive a message that the domain cannot be contacted. Reading more about, I found that I must have copied the MACHINE.SID. The first question: how to prevent (correctly) this problems? Second question: how to proceed when I migrate a NT/W2K Domain to a Samba Domain (note: I'm using a LDAP backend). Regards, Fabiano Felix
