We have installed a member server offsite. We have configured a VPN tunnel between this offsite location and the main office. When I first configured the VPN tunnel everything was working properly, we could ping back and forth, and I could even joined the offsite server to our domain.

Yesterday we had a blackout on our metro e line, so our VPN tunnel was disconnected for a while. After the network connectivity was reestablished, VPN tunnel was back up, but I noticed that the offsite server cannot ping the domain controllers/DNS servers located in my main site, but it can ping and communicate with all other IPs of all other domain computers.

I am banging my head thinking what changed.

Any hint to fix this problem is greatly appreciated.
