Re: Is it possible to create a secure AD environment for widely dispersed PC's behind other instiutions firewalls?

Just to let you know, something similar can be done with different VNC
flavours, such as UltraVNC, using a repeater. Anyhow, this still does not
satisfy all requirements as previously illustrated



Even though we are going through foreign firewalls, we do have a certain
degree of sway with the Network managers' to allow certain traffic. Any
management traffic would need to be sent encrypted so I am wondering if this
could be sent using IPSEC or SSL so utilising just one or two open
ports/protocols.



Any further thoughts?

Chris,
VNC will not work through standard firewalls, but Webex Remote Access
will, because it is an outbound connection to an intermediary.
We manage remote servers fully without using AD.

Many thanks for this. At a simple level, we already use remote management
tools such as VNC to manage some of these workstations, however not all
(because of firewall restraints) can be managed in this way. Still,
remotely managing the desktop is only part of the problem. A central
management point is required that is able to be use to push out key
changes to all desktops, maybe such as would be available using Group
Policy. In addition, some management applications (such as software
firewall policies) require AD integration.

Chris,
AD is only one way of creating a shared security context between
machines. It would not work in your case, as the firewalls will not
allow AD traffic. Something like Webex Remote Access would allow you to
control all the machines.

Or is this even a practical deployment senario for AD?

Hi,

We maintain a wide network of PCs (Win 2000 and XP, approx 200-300
machines). Most of these are single use machines designed for use in a
Video Conference environment. The machines are effectively standalone
with public IP's, and they are deployed in various institutions, some
behind firewalls that we don't manage. Although we have a certain
amount of sway with the other network managers to allow traffic to and
from these machines, we obviously do not have full control over ALL
the traffic that can be passed to them.

I feel that if we can create a secure AD environment to centrally
manage these machines it would be beneficial. I'm not entirely sure
what ports/protocols need to be configured to allow AD traffic, and
then if this traffic can be secured across foreign firewalls.

Is there a way to create such an environment?

Many thanks for any insight or articles you may have.

Chris
