Network Neighbourhood listing in SAMBA PDC

[Yashpal Nagar]

Hi All,
   I have been using samba 2.2.1a as the PDC till now without any problem.
But for the last few days i am not getting network neighbourhood windows
machines listing.
I have the options

OS level 255
Domain master yes
Preferred Master yes
Local master yes

in my smb.conf. FYI this samba is also acting as wins server.
Here interested thing is when i searches for some m/c(in client windows ), it gives me that without any problem.
Can someone enlighten on this issue.

Regards,
-Yash
