Need to bring 2 distinct AD Domains into 1 AD Forest

December 11, 2011 at 14:27:49
Specs: Windows 7 Ultimate x64, 2.4 GHz / 8049 MB
I am starting a new job next week and after having a brief peek at the existing network topology and devices, I have decided to ask the community for a little guidance and opinions.


Current

Two campuses—The main site “Campus A”, with an additional “Campus B”, separated by approx. 8mi (straight-line).
The AD Domains have no connection--each campus is isolated.

“Campus A”:
3 Cost Centers
10MB Metro-E Internet Connection
Cisco Router
HP ProCurve Switches
2 separate (disjointed) AD Domains
3 Servers
Domain #1 [ aaa.local ] (Servers, Users, & Computers)
1 AD Controller / File Server / Print Server
1 File Server
125± Workstations
45± Network Printers
Domain #2 [ bbb.local ] (3rd Party Accounting Service)
1 AD Controller / App Server

“Campus B”:
2 Cost Centers
10MB Metro-E Internet Connection
Cisco Router
HP ProCurve Switches
1 AD Domain [ ccc.local ]
3 Servers
1 AD Controller / File Server / Print Server
1 File Server
1 App Server
100± Workstations
35± Network Printers

Future:
Additional Staff to “Campus A” & “B”
Additional Cost Center to "Campus B"
2 new campuses—“Campus C” & “Campus D”

Goals:
Bring all resources into one AD Forest, to facilitate common user accounts, group policy, and forest-wide access to shared resources.
Implement a forest-wide “Help Desk” ticketing system. (Software already purchased).
Implement forest-wide administration of switches, routers, servers, workstations, and printers from any campus. (Software already purchased)


Questions
What are the community opinions of the best method of understanding the existing operations (network topology, device connectivity, etc.) of both campuses?
What are the community opinions of the best method for collecting information to begin documentation?
What are the community opinions of the best method for implementing an AD Domain Forest?


I’ve been working in this industry for over 25 years, so I’m not looking for a specific “how-to”, I’m just wondering how everyone else is implementing things like this. Don’t misunderstand, I’m always looking for a better way, but at the moment, I’m more interested in implementation strategies and ideas.

Any thoughts?

Thanks everyone.

what are you planning for intersite connectivity?

Q1 do an extensive site survey and document the topology and equipment connections and configurations

Q2 document what programs are used and by whom and at what level of assignment. Server reviews should give you this info.

Q3 from your criteria you want a single forest with single domain. You can start fresh or choose one and then add the contents of the other two sites to it.

Answers are only as good as the information you provide.
