samba and win2k

[Rui Miguel]

Dear Samba users,
I am trying to configure samba in my Red Hat 7.1 box to communicate with my 
windows 2000 machine but so far not totally successfully. After configuring 
smb.conf I can see my linux box in my win 2k "my network" but I can not 
browse its contents. The following message appears every time I try to open 
it:

---------------------------------------------------------------------------
"win2k machine" is not accessible.
The network path was not found"
----------------------------------------------------------------------------

I was wondering if somebody could suggest what might be wrong and/or a good 
reference for seting up samba from red hat 7.1 with a win 2k machine.
Many thanks!
Sincerely,
Miguel
