can't connect to clients using hostnames

[Zig Rave]

i'm running several windows machines and one gentoo linux machine with tinc
and all the windows computers connect and work fine, and they all can
connect to the linux computer fine but the linux computers can't connect to
the hosts if i use a hostname in the Address field.  the hostnames work
everywhere else in the system, and if i use the IP addresses in the hosts
files it works, just not using a hostname of domain name.  Ideas anyone?
