[Samba] Member server: Failed to join domain: failed to find DC for

[Luis Peromarta]

Magically, upon restoring from earlier snapshot, with the exact same config ,


root at member:~# net ads join -U"MAD\Administrator"
Password for [MAD\Administrator]:
Using short domain name -- MAD
Joined 'MEMBER' to dns domain 'mad.mater.int'
DNS Update for member.mad.mater.int failed: ERROR_DNS_UPDATE_FAILED
DNS update failed: NT_STATUS_UNSUCCESSFUL

root at member:~# net ads leave -U"MAD\Administrator"
Password for [MAD\Administrator]:
Deleted account for 'MEMBER' in realm 'MAD.MATER.INT'

root at member:~# net ads join -U"MAD\Administrator"
Password for [MAD\Administrator]:
Using short domain name -- MAD
Joined 'MEMBER' to dns domain 'mad.mater.int'
DNS Update for member.mad.mater.int failed: ERROR_DNS_UPDATE_FAILED
DNS update failed: NT_STATUS_UNSUCCESSFUL


I really haven’t a clue why it failed before.
