2 domain controlers for IP phones
I need some help. I amtrying to figure something out. I have IP phones, two offices, two firewalls, and two domain controlers. My phones in officeA are hitting my DC in office B. My IT guys say it is normal but Idon'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 touchDC A and the pc'sand 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.Thanks!

What system are you using for IP Phones? For example a Cisco solution. Cisco can be configured to authenticate against AD, so I would expect some lookups. Andrew Sword, MVP

Another think to consider is the phones are looking up AD for DNS? Andrew Sword, MVP
