RE: Network Monitoring

You should protect your network at layers 2 and 3  (configure your
routers with ACL's etc).

I would also like to know of a way that you can connect to a workgroup
from a domain environment without disjoining the domain (to check it out
;)). Any Ideas?

Dear all,

I want to have a monitoring tool for viewing the active workstations and
at the same time I want to have the ability to block any suspicious
workstation from accessing the network (Based on IP address). I also
would like to have a list of trusted MAC Addresses, so that any device
that gets connected to the network without being in the trusted MACs
will get blocked or if not, I get notified about the newly attached
workstation...

Is their any software that can provide me with these requirements, or it
might be a collection of software.. we are using Windows Server 2003 if
that helps ..
