Adding IP ranges when active directory /DNS spans locations?

[Boe Dillard]

Hello,

I swear I used to have to add subnets in dns or active directory when connecting multiple locations across a VPN tunnel but for the life of me, I can't remember where I added that subnet information.

For example office A in NY is 10.10.100.x (internally)

Office B in  CA is 10.10.200.x (internally)

I can't remember if it was in sites and trusts or DNS but I'm pretty sure somewhere I need to add the second subnet information.
