There is need that I ascertain the complete control of our sites’ replication. The way I have been controlling is by ensuring replication can only be done in one way. What I need to know is whether this is able to manage all data traversing the communication ports for our two DCS.  I understand that IPSEC tunnels are able to restrict the number of accessible ports required on the firewall. I also understand that it is possible to unencrypt it for the IDS/IPS to still manage the flow of traffic. But how this done? Your advice will be highly appreciated.

Our organization desires to combine our active directory forest islands into one active directory forest with a root domain. The root domains will be maximum two. Apart from two or three forests that are used in offsite replication for DR purpose, the forests are separated by firewalls and do not communicate.

The cause of our problem is that our current setup is such that a lower security area cannot start communication with a higher security one. A two way communication is only possible when initiated by a DC in high security area. Is there a way of providing security that allows DC to DC communication two break through firewall? Help us.

After recently acquiring a product platform for my organization, I have a concern that makes me seek assistance. This is about how we are to store data on our customer authentication. After weighing a number of options, we decided the most convenient and cost effective way is an active directory, for which we have a support team. Later, though, we may have to go for a simpler more sustainable option, and this is the real cause of my worry.

How do we retain our current clients’ passwords bearing in mind that we may need to change servers?

We have a LAN at my work place whose set up is peer to peer. Among the workstations is Win XP, Mac OS 9, Mac OS X and Win 2k3 operating systems. There is also a front server and a netgear router that is meant to support the Domain net System and Dynamic Host Configuration Protocol (DHCP) network. It happened that on time the router broke down and as a result all connections to the LAN and internet were severed.
