Is there anyway to stop users from being able to create an ad-hoc network? I can keep users from connecting to them via GPO and that works well, but they can still create one. The problem with this is some of our less tech savy users (at home) think they are "connecting to a network" when in reality they are creating an adhoc network, and confusing themselves, loosing all network connectivity etc... -Dan

No policies can disable the ability to create AD hoc. AD hoc works with WLAN AutoConfig service. You can disable this service and see if it helps.

that doesnt help :) What other things does the Wlan AutoConfig service do? Would I be breaking anything? I can lock them out from changing any adapter settings, but they can still create a new network :) ughh... -Dan

Hi, Disable WLAN AutoConfig Service may be only an optional workaround. WLAN AutoConfig Service controls not only AD-Hoc, but also other kind of wireless connections. WLAN AutoConfig Service If you cannot disable the service because of some reasons, there are no valid methods to disable AD-Hoc on clients. You can also consider deleting AD-hoc connections when a user logs off or logs on with the command “netsh wlan”.

Dear Dan Did u try it cz it works :) :) Damien

I did not try it yet :) I have to do a lot of testing first before I do something crazy and deploy it to 600+ clients :) From reading the service description it appears to do a lot more than just ad-hoc - it appears to handle all 802.1x stuff as well, this would break many things in our environment if this is the case... -Dan

Hi, According to the introduction, the service only manage IEEE 802.11 connection for connectivity to ad-hoc wireless networks, small-office wireless infrastructure networks. You can just give it a try since no other methods can help on our requirement.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Well disabling the wlan auto config server disable all wireless access. So I dont think that is a good option. -Dan

Hi, After researching on Netsh command, I found that we can add a filter to deny AD-Hoc. The command should be : netsh wlan add filter permission=denyall networktype=adhoc Please give it a try.
