Samba (DNS?) problem

[Santiago Cepas]

Hello everybody.
I'm trying to configure a public folder in my linux box that can be
accessed by other window machines in my local network. However i'm
unable to make it work.

I've been googling and reading and come to the conclusion that i'm
having a DNS problem. When I do
	ping WinMachine
I get:
	ping: unknown host WinMachine

However when i ping the ip address directly, everything works find.

I guess i'm doing something dumb here.
Any help?

Some info:

# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
search Cybes3
nameserver 192.168.200.254

# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:0C:F1:D7:2E:BD
