Check that the server can ping the clients and vice versa.  Also check
the netmask on the server and clients to make sure it is correct
(probably 255.255.255.0).  Have a look at the hosts allow/hosts deny
parameters in smb.conf to make sure that they are not restricting
access to some of the machines.
