PROBLEMS connecting to SAMBA

[santosh shedge]

Hi

I have a machine on which RedHat Linux  6.2 is installed. IP address of
machine is 10.5.2.180
We have an intranet in our office. My neighbouring machine has IP
address 10.5.2.179
My workgroup name is  MCIA
I'm giving netbios name as ''LINUX_SAMBA" which appears in my neighbours
machine in network
neighbourhood after I UP the samba server.

When my neighbour clicks  on it it asks for  user name and password.

My smb.conf file is something like given below

Question:  What is the problem that I can't  log onto samba from my
neighbouring machine.
