Re: [Samba] error with joining new DC to domain




Thanks Rowland for your answer. 

these are sernet-packages from their subscription. 

There are 4 DCs (all with last sernet-rpms) 2 are demoted with probs
(dc-01 and dc-02 both centos6) and 2 are running (dc-10 and  dc-11 on
centos 7) 

dc-11 has all  fsmo. joining with the old dc-01 and dc-02 doesn´t even
work. 

dc-01 joins but gives me this:
