I use my ISP's dns servers as the default. However, I would like to send all DNS queries for sampledomain.com to dns server x.x.x.x. My home network has a site to site VPN to x.x.x.x where all sampledomain.com resources are included.
In other words, any request for mail.sampledomain.com or spoint.sampledomain.com should be requested from x.x.x.x. Putting all these in the hosts file will be too cumbersome as I don't know all of them and there may be a few hundreds. Is there a program or windows functionality that can help me achieve this?
