Nec US100 thin client does not connect

[gertk]

Hello,

I have been trying to get two NEC US100 thin clients to connect to my server (Ubuntu 12.04 with Virtualbox 4.2.4 in Headless mode, ) but so far no luck. Connecting from another PC (Ubuntu 10.04 with rdesktop) is no problem.

This is what is stored in the log:
