Hello,

My company is working on enabling wireless on our users
laptops for use on the road. We do not at this time (nor
have plans for) wireless networks in our corporate or
regional offices. Our network admins do not want to allow
users to have the ability to network their laptops via "ad
hoc" mode so I've been tasked with finding a way to
disable this. I was hoping to find a method of doing this
via policy, but so far, I haven't found anything at all.
We will be using a personal firewall, but the security
risks of ad hoc still worry our admins. I've been looking
at Windows XP and it has a nice little switch that allows
only access to infrastructure devices; 2000 does not.

We're working on IBM Thinkpads (A31/R40/T41/R51) all with
internal WNIC's running Windows 2000. Only the R51's have
a setting on he driver for the WNIC that allows you to
disable ad hoc networking. Most of our users don't have
admin rights so this would work well enough if the drivers
for all the WNIC's had that option, however they don't
(I've checked all the updated driver versions).

My questions are:
Is it possible to disable ad hoc networking on wireless
laptops running Windows 2000 SP4 via policy (or other
ways)?
What are others doing to address the security risks of Ad
Hoc networking?

TIA for your insight,
Josh
