Hello,
Banning particular IP addresses is useless to us... We need to ban
particular users.
For example, if we ban fred's machine, fred can still log in from a
different machine. We need to ban fred from every machine, but he still
needs to be able to log into other machines on the network.
Thanks again,
Richard.
