Do you have any information to support that this is
still a relevant
issue?  Thanks!

There are many ways to
"jump" vlans with in a switch.

If you have any manage switches, you could put
them on separate VLans,
and
deny them access to your private network...

My two-cents

Subject: information harvesting from within the
network

Background:
I work in a university that has university typical
security practices.
Currently any authenticated user can scan the
parts of the network with
tools like LANguard or Nessus and obtain a
considerable amount of
information from them.   Most of the computers in
our network are
windows
computers.  We also have departments with MACs and
*nix machines.

Goal:
If possible, lock down the Windows computers with
group policies and/or
templates to disable this potential unauthorized
information harvesting
users and then restrict scanning ability to the
security group with LDAP

permissions.  Am I on the right track here?

I would like to achieve this without using a host
based firewall.

Group policies have large pool of settings to pick
from.  Narrowing it
down
to a few that disable at least portions would be
appreciated.

Thanks,

ddjembe
