I have 11 offices that connect through a VPN to a Windows Server 2003 domain controller running Active Directory in our headquarters.
This may be a stupid question for someone who has been running this domain for several years to finally ask but I have all of the computers in the remote offices DNS pointing back to the domain controller. Am I correct in doing this? I was always under the impression I had to in order for them to connect to the domain but the problem is when the internet service is slow in headquarters if affects service in the branch offices because their DNS points to headquarters. Also, if the remote offices are using a lot of bandwidth (streaming video, etc...) and their DNS is pointing back to headquarters are they in fact taking bandwidth away from headquarters? Am I making any sense? Thanks for any light you can shed. I have always been confused by DNS.
