'This week in third semester CNT, we stepped up our class's lab activities. This week’s goal was to simulate a real business networking environment.
We set up an environment that would simulate a medium-to-large-sized company, which would have three networked sites. These sites in the real world could represent different branch offices in different physical locations.
For example, if Ranken were the simulated company, St. Louis would be the main site, or headquarters – then suppose Ranken had branch offices in L.A. and New York, those would be set up as separate sites also. Physically they would be separated by WAN (wide-area networks) links and logically they would be set up as different branch offices in Active Directory.
This week I learned a lot of mind-boggling information about how to set up three completely different domains in a logical forest, and configure these domains as child domains to a parent domain. If that sounds complicated, well that’s because it is. However, I think this was a great learning experience.
I also learned how to install a server and configure it as a DNS server, global catalog server and Forest Root Domain Controller. Now it might sound as simple as click the "install" button after inserting a program CD, but I’m afraid it’s not that easy. The first step is to install it, yes, but after that the task is to get the computers and users to talk and communicate with each other. That in itself is a whole different ball game when talking about replicating or copying information to different servers, and making sure certain users have access or don't have access to certain resources. That was my biggest problem when setting up this lab. In order for a server to use certain resources and create a centralized user account on the domain in Active Directory, the DNS server and Global Catalog server had to be already up and running and replicating before my server was turned on.
I’m not going to go too deep into the specifics but like I said I learned a lot. And in fact since I ran into so many issues and problems here at Ranken on this simulated lab, I am confident I won't make the same mistakes in the field in a real environment.
