Network name resolution problem

      Microsoft OSs will always show the machine name regardless of the
existence of DNS or not. Where's your DNS server for your private
network, if your IP addresses are assigned by DHCP is the DNS server set
to dynamically update, have you tried fixed IP addresses and an entry in
/etc/hosts. What's the output from nslookup or dig.

Subject: Network name resolution problem

Two machines, both dual-booting WinXP and FreeBSD (one 4.9, the other 
5.1), networked through a Netgear switch with an ADSL router/modem 
(Zyxel Prestige 650R) providing 'net access and is also the DHCP server.

Under both OSes both machines can access the 'net with no problem and 
under XP both machines can see each other (i.e. the other machine 
appears, by hostname, in Explorer). Under FreeBSD however, both machines

can see each other but I can only use IP addresses to communicate:

/usr/marko{57}% ping redshift
ping: cannot resolve redshift: Unknown host
/usr/marko{58}% ping
PING ( 56 data bytes
64 bytes from icmp_seq=0 ttl=128 time=1.036 ms
64 bytes from icmp_seq=1 ttl=128 time=0.651 ms
64 bytes from icmp_seq=2 ttl=128 time=0.641 ms
--- ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.641/0.776/1.036/0.184 ms

Obviously this is a PITA with dynamic addresses. Is this a config 
problem with the router (i.e. should it be acting as a name server for 
the LAN side) or with my FreeBSD configuration? Four hours of searching 
the 'net has not yielded the answer.

Any ideas anyone?
