I got Linux DNS server running years ago, and we're trying to add an Active Directory server on the network.
The AD is congigured to have static IP, and a DNS A record pointed to it.
Now, as I try to join a client to it, it fails. If I use the domain name, xxxx...., it will fail completly, as it says it can't find the controller to it. If I use the NetBIOS name, I get a prompt to input my account information, but then failed.
How to fix this?
