Yes, I can ping the TS-host (like every other host) over the hostname
and over the IP-Adress to. There is no difference between the two ways,
same latency etc.
As I told, the TS-host is also reachable with VNC  but not via RDP and
with the NCP client RDP works fine to. That's what I mean with "strange";-)
I tried a few hours with many different configuratons , so I can provide
a lot of informations - what ever you need;-)
