samba - Feb 2004 - Queries regarding samba usage : sharing files with Win NT/2000

sir
i study in an institute where the PC's have either Win 2000/NT
RedHat 7.2 . I have been trying to set my PC such that can be
mounted / accessed from every other PC in the lab but am unable
to do so. I am also unable to share my files over the network.
I read the 'smb.conf' file and did required changes . When i
access this PC from other PC's , it comes to connecting menu but
does not accept any passwd. Moreover, my PC does NOT have any
/etc/samba/smbpasswd file.
What do I do ??
Seeking ur help...
