Why can't our non-domain clients connect to one (out of three) terminal servers!???
We have 3 2008 terminal servers - in a session broker farm. Following a power outage one of the three is not allowing connections from non-domain machines.
Domain machines can connect to all servers as normal.
The problem doesn't lie with the network, I've connected one of the windows 7 clients to our standard network and it can ping the relevant server.
The problem does not lie with dns - I can ping by domain name or by ip address.
The port 3389 is shown as listening on the server and has exactly the same binding as the other machines.
Group policy is the same on all servers.
