I work in a hospital that has a Win2003 domain. We also have a wireless
network using 802.1x, WPA with Cisco AP's. We use IAS as our remote access
server.

We have two groups of wireless workstations, one group of medical stations
and another of admin stations. We want medical personnel to be able to use
either medical or admin workstations but we want admin personnel to be able
to use only admin wireless workstations.

At first I set up mulitple groups. One group consisting of computers and
another of users. Then in the remote access policy I stipulated that to gain
access the connection had to come from the right computer group and right
user group. Sounds OK but it does not work. If I include a group that has
only computers in it the wireless connection always fails. No problem if I
only have groups with users.

How can associate a specific user group with specific computer group when
using remote access for wireless connections??

Why IAS? Why not just have them as Domain Members and forget it?

This really is not "remote access".
The wirless portion of the network is not a "different network". A WAP
does not create a "network",...it just replaces the physical "patch cables"
with a Radio Signal. It is effectively just a Switch without wires on the
Host side,...but is still wired on the "backbone" side.

1. Let the machines connect to the WAP using WPA with a Key,.....without an
kind of "user authentication.

2. The machines need to be Domain Members

3. In "Active Directory Users and Computers" go to the properties of each
"Administration Personnel" account involved in this and set a "list" of
machines they are allowed to connect from [Yes, it's a hassle],...you can't
do it with Groups. The users need to log into the machines with Domain
Level User Accounts,....not Local User Accounts. Active Directory will then
evaluate if the user is allowed to log in with that particular workstation.
Remove all local user accounts from these machines except for any that
really have to be there.

We need IAS to handle the remote connections from the wireless workstations.

There is nothing remote here. The WAPs are connected to your local
LAN,..therefore any machine that uses them is local. The WAP serves the
same function as a LAN Switch but without the wires.

To control who can log into what machines as you describe you want to
do,...the machines need to be Domain Members and the users need to log in
with Domain Accounts. Those Domain Accounts need to have the list of
"approved" machines added to the Account Properties. Being "wired" -vs-
"wireless" is totally irrelevant to this aspect of what you are asking.

All the "security" on the WAP serves one purpose,...it protects the Radio
Signal,...that's it. Some high-end Wired Switches have a "comparable"
function with their Port Access Control (802.x? I forget..). But with the
wireless using WPA with a WPA Key, in my opinion, is perfectly
sufficient,...someone would have to drag me a long way kicking and screaming
over broken glass to get me to feel that there was any need for using IAS
with user authentication just to establish authorized contact with a "Radio
Signal" instead of just using WPA with an encryption Key.
I know some would disagree with me,..fine,..there always are,...but that is
my recommendation and I feel pretty strong about it.

I realize that medical facilities make heavy use of wireless due to the
convenience of mobility and not having to run cable (and then moving the
cables everytime something is remodeled or moved). But all the wireless
does is replace "wires" with a "radio signal", it is not creating a new
network, it is not a separate network, and it is not "remote".

I disagree with you. WPA with a static key is not sufficient security.
Enterprise level wireless with dynamic keying gives us the security we need.

In the end it doesn't matter here. Your question/goal really has nothing to
do with wired -vs- wireless or any wireless security techniques.

To control who can log into what machines as you describe you want to
do,...the machines need to be Domain Members and the users need to log in
with Domain Accounts. Those Domain Accounts need to have the list of
"approved" machines added to the Account Properties. Active Directory will
then
evaluate if the user is allowed to log in with that particular workstation.
Remove all local user accounts from these machines except for any that
really have to be there.
