I have a small WS 2012 R2 domain at work with 8 Win 7 pro workstations.
At home I use openvpn & tightvnc to connect to the domain from a win 7 pro box and log onto any machine. VPN and TightVNC work perfectly
Just put in another win7pro box at work. Domain controller sees it, other workstations see it and I can connect to it on the local lan from any other box with tightvnc. Can ping to and from.
At hone I cannot ping or connect using TightVNC or remote desktop. Can only access the box by logging into another box with TightVNC then instigating a session to the new box. This works, but the latency is a obviously a problem, and doesn't solve the primary requirement of a direct connection.
Can't just pop into work, its a 25 mile round trip, so really need some pointers as to where I need to look for issues. I am thinking its windows firewall, but can't see anything different from the other boxes.
