New Exchange Design

Hi,

 

I need some help in my new design and check the new network topology.

 

Here is my current topology:

1- I have a head quarter in Jordan ( 2 AD 2008 , 2 Exchange 2007 clustered, 2 HUB/CAS , 2 ISA server NLB ) and about 30 branches , 10 users in each branch.

2- All users in HQ1 ( 250 users ) and users in the 30 branches are domain users and connected to AD and exchange and ISA in head quarter.

3- There are no servers in branches.

4- This setup is running perfectly without any problems.

 

Future Setup:

 

1- In another country I have 1 HQ2 and 5 branches each branch consist of 10 users

2- HQ in Jordan is connected to HQ2 in another country by leased line 1 Mbps.

3- All 5 branches are connected to HQ2 in that country through leased lines.

4- All users are in workgroup environment.

5- I need all users to be connected to the same domain and exchange servers and Antivirus server in Jordan.

6- I put a design which is to put 2 RODC 2008  and 1 Exchange 2007 and 1 ISA 2006 and 1 Antivirus server in HQ2 in that country and all users in are connected to servers in HQ2.

7- Servers in HQ2 are connected to servers in HQ1.

 

What you think about this design, is it recommended or I can connect all user to my domain directly without using additional RODC , Exchange , ISA and Antivirus servers.

 

Is it enough and will give the performance I need (Authentication, Applying policies, Mail flow , Internet browsing and Antivirus updates)?

 

Regards

Nasir
