Please refer to the attached Visio diagram.
The network at our Houston HQ was set up with two DC integrated with AD and DNS to handled logins for the software development environment and DNS. We have just recently moved our production servers to a data center in Dallas. There are also two DC integrated with AD and DNS in our Dallas data center, which are used for remote user, clients and disaster recovery. Our users in Houston are complaining about slow terminal service sessions, how long it takes to login into the network, name resolutions of servers and network resources and internet sessions timing out.
I need to know what the best practices are for setting a Windows 2008 R2 DC integrated with active directory and DNS for this network. My main concerns are:
1. Setting up the forward queries to the outside networks (Google searches, browsing the Internet).
2. The NIC configuration or any other DNS tweaks/ configs that address the issues we are having
3. Should we use our ISP’s DNS for the alternate?
