SAMBA question

Hello,

I just configured SAMBA on one of my RH 7.1 boxes. The problem is --
whenever I try to browse the network neighbourhood, I get

*******************
linuxhome.com(my internal domain name) is not accessible
the network name cannot be found
***********************

But I am able to map the share, access the folders and files without any
problem.


RELEVENT LOGS
My log.nmb has following in the log

**************************
Samba name server SNOOPY is now a local master browser for workgroup
LINUXHOME.COM on subnet 192.168.0.254
***********

My charlie.log shows (charlie is the Win2k Advanced Server from which I am
trying to browse the network neighbourhood)
**************************
[2001/12/24 14:46:15, 0] smbd/password.c:authorise_login(831)
rejected invalid user nobody
**************************

How do I fix my nmbd?
