samba - Sep 2003 - I cannot find the linux machine name from the win2000

Hi all,

I have install the samba on my linux computer, and reconfig the smb.conf, but I
cannot find the machine name from the win2000(another computer), from the
win2000, ping the linux IP is OK, but the ping the linux machine name does not
work; from the linux, both pinging the ip address and the machine name of the
win2000 is works.
So, what is problem maybe ?
I install the linux(redhat 7.2) with workstation version, should I change it
into server version?
Thanks!

Kang
