Cannot Join to AD DC via samba

  • 772

I'm trying to join my CentOS 7,64 bit server to an AD DC and I'm using the following command:

# net ads join -U <username> -S <target server>
Enter <username's> password:

But after long time, I get 

Failed to join domain: failed to find DC for domain <name>

I'm not sure whats the issue. But I have another server of same specs connected to this AD DC successfully.

I guess it could be the network issue, because from the another server ( which is already joined ) I am able to telnet to port 389 and 53 of AD DC. But from this server I cannot telnet those ports of AD DC server but just ping.

So is this issue due to network ( port block ) or something else? I assure that both server has similar config files.

  1. But from this server I cannot telnet those ports of AD DC server but just ping.

    Then problem at least in network connection. Check the document that you have opened all needed ports between the client and AD DC.
