Network Infrastructure

Hi Guys,

Hope Im in the right group.

Im in a stage of fixing my network. This is my current setup.

1. I have an active directory server, which is mydomain.com, wherein
also my DNS and DHCP is located.
2. My subnet is 255.255.255.0

This is my idea.

1. Have these servers: (Need suggestions on these)

a. AD Server with DNS Server - is this a good practice?
b. DHCP Server with ISA Server - is this a good practice?

Other concern:

I want my network to have access limitations. Here is a scenario.

1. In our network, only managers can use their laptop to access our
network and internet. It can be wired or wireless. Unauthorized laptop
should or must not access our network. But from the way the network was
setup, they can access it through wire. I can filter the wireless using MAC
Address filter from the routers. But if they connect through wire and know
how to config TCP/IP they can easily access our network. Can this be
avoided through ISA? Is there a way to filter MAC Address through Active
Directory?

Hope you can help me on this.


Thanks in advance.

Allan
