Linux Machine Not Shown On Particular Windows Machine

[Silky Mittal]

Dear Sir,
       when i give the command "nmblookup -d 2 '*'"
IP addresses of not all PCs in the network are
shown only some of them are shown.And so if i try to
access the Linux machine from the computer which is
not
shown its not accessing Linux Machine moreover it is
not even showing it in the network neighbourhood of
that machine but when i telnet from Windows Machine to
Linux Machine it works fine.I'm having Red Hat 6.2
in my computer.Help will be appreciated. 
Thanking You,
Regards,
Silky.
