2 domain controllers and IP phones in both locations RRS feed

  • Question

  • I need some help. I am trying to figure something out. I have IP phones, two offices, two firewalls, and two domain controlers. My phones in office A are hitting my DC in office B. My IT guys say it is normal but I don't trust the answer. It is not like it is every once in a while it is all day every day. My thoughts are that the pc's and phones in A should only touch DC A and the pc's and phones in B should only touch DC B and then DC A and B should talk to each other. I not tech trained so I need you help. :) Some of my PC's in A are also hitting DC B but it is just every once in awhile.

  • What do you mean by 'hitting the DC"?  Are you running OCS on these systems or are you referring to some other AD authentication or LDAP lookups supported by your VOIP devices?  Depending on  the network configuration and bandwidth it's entirely possible for workstations to communicate with either DCs, but the closer system is usually the preferred target.
