Just some random thoughts:
Have you checked your ipchains (firewall) settings? Redhat 7.2 installs 
with firewall enabled as default - check that ports 137-139 can get 
through to your workstations.
Win95 can do encrypted passwords by updating with (all) the security 
patches (don't know if you should also employ some registry hack - look 
in the samba doc directory).
Remember that the users has to be in both passwd and smbpasswd when you 
do encrypted passwords.
Check that the user in smbpasswd is enabled (no D in the field to the 
right) and has a password
Check the "hosts allow" in smb.conf
Make sure that "smbclient -L //server_netbios_name" works before you try 
from the Win95 and Win2k workstations.
Set the log-level higher (e.g. 3) in smb.conf and look in the logs when 
you try to connect.
