Karl Gechlik — Fri, 17 Sep 2010 15:14:25 +0000

How
can we use Windows 2008’s Network Access Control to limit intern’s
computers from getting to the Internet? Where is this feature setup and do
we need a client on the computers or does AD take care of this?

Can you explain network access control in Windows Server 2008 R2 and how to set it up?

NAC and Wireless Controllers

Tankman — Mon, 21 Jun 2010 18:40:57 +0000

I have a need to setup conference rooms that will be used by both corporate and foreign or guest devices. I would like to use wired and wireless for flexibility and video conferencing. NAC seems like a no brainer but am curious if I should look into a Wireless Lan Contoller device of some sort too? Wouldn’t a NAC do the same thing as what a WLC would do?

802.1X

What is the difference between NAC and 802.1x? Can you implement 802.1x without NAC? My understanding is you could implement a NAC solution not utilizing 802.1x but not the other way around.

Thanks

NAC and Static IP addresses

Serviceguy — Wed, 16 Dec 2009 15:13:27 +0000

Can you use a static IP network addressing scheme (no dhcp) with a NAC solution? It was my understanding that NAC works best with DHCP

Is that true? Anyone today using a static IP network with DHCP?

I am doing NAC research for my company to see what would be the best solution to implement it. We having serious problems with managed and unmanaged users coming onto the network which spread alot of viruses, thats why we need control who is coming onto the network.To give you some background info this is what the landscape looks like.

There is a total of about 12000 users in our company
We have an Enterasys backbone not all of the switches are 802.1X compliant i would say 70% is.
We running Microsft environment, the hosts are running Vista and XP , servers are 2003 and a few 2008. We will be migrating to 2008 over the next 18 months. We have System Center Config manager doing our patches.We just implemented microsoft PKI.
Symantec SEP11 is our AV software.

What i was task to do is see if we can utilise our existing investment in implementing NAC and the cost associated to that and what a complete new solution other that what we have would cost to implement.

My dilemma is knowing what all the vendors offerings are what would be the best solution for us to go with?. Is it out-of-band or in-line or both ? There is so many many things to consider and just feel overwhelmed at the moment with all the options.

If anyone can assist in this decision i would really be gratefull.

Can any one provide a step by step guide please to solve this matter and oblige the user of that computer to log on with a user name and a password each time he clicks the icon ?
