We currently have 2 remote sites that are connected to the main office via VPN. They all have Sonicwall appliances for security and to maintain the VPN connections. At one of the locations adding a pc is simple, just add it and if logged in as a domain user they have access to all network resources from the main office. The second location, however, in order to connect these users to the network I have to specify the DNS servers in network properties. Without this they can connect to the internet but not our network. What am I missing?
