At our small business, we have a server running Windows Server 2008 that acts as active domain directory, DNS, and DHCP, and a SonicWall router running our VPN services, with SonicWall NetExtender as the client software. Our problem is that when someone is connected through the VPN, they cannot initiate communication with anything on our local network.
SonicWall shows that the user is connected. The DHCP on our Windows Server 08 machine is telling me that he's been given exactly the address his NetExtender client says he has. I am able to ping the user from both my computer and the server he's trying to access, but his pings are timing out. I cannot remote desktop into his machine, either.
To my knowledge, there has been no change to either the server or the firewall. Yesterday, before an area-wide internet outage, he said he was able to connect and access the files on our server just fine.
What in the world is going on?
