[Samba] cannot browse domain

[Terry Wong]

i have tried redhat 7.3/8 w/ samba 2.2.5/7 which everything seems work fine
except i cannot browse the samba domain. the log files say:
[2002/12/11 13:43:52, 0] smb/password.c:authorise_login(863)
  authorise_login: rejected invalid user nobody

after i tried to browse the domain from win98/xp station, and win98 windows
explorer say
Mydomain is not accessible
The computer or sharename could not be found. Make sure you typed it
correctly, and try again.
i think this is to do with the authentication part, anybody has face
something like this? or can this be hadware problem?
