I had the same issue and have found a workaround.
The problem is that NetBios is not working properly for some reason.
If I use another DHCP with "wins" setting, everything works just fine. Also when I enter the "wins" setting manualy in the TCP/IP setting pointing to ebox, it works as well.
This might have something to do with the unusual usage of ebox. It is not a gateway, but it is a DHCP server for 192.168.0.0/28 with IP 192.168.0.3, 192.168.0.1 being the gataway.
The instalation was made with 0.11.101 installer, manually upgraded to latest ebox repostory version (at the time of writing).
