Hi Antonio,

The resaon why AD is because the current network is an NT network and porting to AD should make it more secure and make our life easier with the Group policies on the student's machine....

The current setup is pretty bad, the students are located on a different vlan than the staff and there is a one way trust relationship between the students and the staff domains. However, the students servers(PDC and Exchange) have had dual NICs for years between the staff and the students network which is pretty insecure. The reason to have dual NICS was to provide the teachers with access to the students home folders and to be able to share the GAL.

I am fairly new to NT/AD so I am not sure what the best design would be. I had in mind isolating the servers on Vlan A, the staff on Vlan B and the students on Vlan C but I am not sure what is a good AD structure for the whole thing making it as secure as possible, removing the dual nics and still be able to access the students home folders and share the GAL. Having  a different domain for students or having a different OU within the same domain ....
