LinuxBox can't appear in Net neighbourhood.

[big_tiger at 371.net]

I have samba 2.0.5 run on my RH6.1
In windoz,when I use "find computer",I can find it without any difficulty!
Also I can access it using this method!
But I can't see it in network neighbourhood!
I've tried "net view /workgroup=MY_LINUXBOX_DOMAIN",still can't see.
Why?(In my linuxbox,the dns resolve doesn't work.does that matter?)
The following is my global section
[global]
workgroup = SOME_DOMAIN
netbios name = MY_NAME
public = yes
server string = COMMENT
hosts allow = OUR_SUBNET
security = share
encrypt passwrods = yes
socket option = TCP_NODELAY
interfaces = MY_IP/SUBMASK
local master = no (I also have tried "yes")
domain master = no (I also have tried "yes")
wins server = WINS_IP_OF_OUR_SUBNET
-------------------------------------
All other items have their default!
