I am wanting to setup the other locations with the ability to connect to their local server while we are in the process of moving our data center to another location.
The local server is pointing to itself with dns installed as a secondary dns and replicating normally.
The secondary dns is the isp primary dns server.
Users can access the internet but cannot access their local server shared folders when our vpn tunnel is down.
do I need to install active directory on the local servers?
If so, is there another way to do this?
