Hi All, I'm hoping someone on here will be able to offer some words of wisdom...... I'm just going through a mock exam paper as I have the actual approaching, the scenario calls for me to set up 2 small networks both consisting of: A server configured with AD,DS, DHCP and Email, create 5 user profiles with relevant folders and paths. 2 client machines that will obtain their IP's from the server, allow users to log on to the domain and send/receive emails to and from other users on their domain.......... All of the above I've done with no problems, my problem starts further down as it states that I have to "Configure Network A to allow limited access by nominated users on Network B" and "Configure email to allow email communication between all users on both networks" All of the above is being done in a virtual environment using Oracle Virtualbox so using a router isn't an option for me, and as an added kick in the teeth we haven't covered RRAS in the course yet, I have attempted to use RRAS with static IP routes but I can't find anything that goes through it the way I need it to work, most stuff talks about using a router.... Anyway....thanks in advance for taking time out to go through this post, I hope it's clear enough for you to understand what I need and I hope someone can just make me look a complete dope and say "do this........ and you're done" Jon
