Active directory TO

I am unable to set up communication with Domain Controller with my TO.
What do I need to set up in order to allow communication with a controller?
Is there possibility to allow all communication generally within LAN?

thank you

Hi, what exactly do you mean by setting up communication of TO with domain controller?

How do you want them to “communicate” together? You mean user authentication or 802.1x or something like that?

AFAIK there is nothing blocked (no firewall rules) in LAN zone by default.

EDIT: I don’t use domain controller at home so can’t help much but don’t you need to setup WINS or NetBIOS or something like that?
