Site to Site VPN not allowing access to network
I am not very familiar with Sonicwalls, and I have a client with 3 sites, all tied together with Sonicwall routers running OS version 220.127.116.11 using a VPN. They used to have a domain but the domain controller is now gone, and all computers are out of the domain. Now, they have just a file server, and no one can access it from the other 2 sites, but they can access it fine from the site the server is in. They never could access any of the computers at the other sites but they could always access the domain controller, no matter where they were. Now, the new server has the same ip address as the domain controller, but no one can access it. I have even called in the builder of the VPN's and he does not know why I cannot access the server (even by ip address) from any other site. I have been working on this for days, and I have tried MANY things but no go. Help please?
