Domain group policy(windows 2012 server ) applied on the clients ( windows 7) to prevent them using wifi, they got this message "your network administrator has blocked you from connecting to this network". Is there a walk around to by pass this policy from the user?
Thanks

I'm sorry but i don't really understand the question.
You say that there is a policy in place that disables users to use the wifi network and now you would like them to be able to use it?
Or do you want to bypass this policy on your machine that an administrator has set?

If it is the first, yes this is possible, you should then disable the policy that disabled Wifi. You have access to those policies?

If it is the second, then no. If an administrator set up a policy there is no way around it.

It is for testing purpose.
The policy applied from domain group policy
Can the user bypass the policy , if he is local admin on his windows 7 machine so he can use the wifi?

Nope he can't. If a policy is applied it will be applied to all users because normally (by default) a policy is applied to the Authenticated users group.

The only thing you can do is give this specific user you are testing with permissions on the GPO and give him (or her) explicit denied permissions on the apply policy. This way the policy will not be applied to this user. Do keep in mind that no setting from this policy will be applied because you are denying it explicitly.

If I have a user traveled to another country and he is asking me to remove the policy from his laptop or reset the policy to the defaults , so he can connect to wifi ,knowing that he is local admin on his machine, is that possible?

Nope, still not possible.
The problem is that this policy was applied when he was logged onto the domain. And because this is a domain policy the user needs to have access to the network before he starts up the machine.

The only possible reason to get this fixed is the let the user use a VPN connection that can be established before login (select use dial-up connection to log into the domain) and after he is connected to the network let him do a GPUpdate /force. If the user can't make a VPN connection, has the policy applied and is not in the office there is no way of disabling it.


The only option that might just work (but i thought this doesn't work) is to create a local user account and log in with that local user account. It could be that the policies will not be applied then. You do have to check if this might be a possible workaround.

as a local admin you can overwrite policies with gpedit.msc if you know which switch he has to change he can do. Domain policies are only changing policies to a domain default but you can not prevent local admins to change them. Its a concept. 99% of all companies uses local admin on NB. But why??? If you goolge its a never ending story about.

By the way its USER CONFIGURATION / ADMINISTRATIVE TEMPLATE / NETWORK CONNECTION / Ability to enable/disable a LAN connection

If he opened up the gpedit.msc he needs to go to the User Configuration and beneath the user configuration you have 3 options, 1 being Administrative Templates. After that he needs to go to Network, then to Network Connections and then choose "Ability to enable/disable a LAN connection" and set it to enable.

After that he needs to go to a command prompt and run gpupdate /force. After that let him reboot and he should be able to change the wifi setting.

Btw, do you have any idea what policy is applied on the policy in the domain??

These are the settings that need to be changed.


User Configuration -> Policies -> Administrative Templates -> Network/Network connections ->

Policy | Setting
Prohibit access to properties of a LAN connection  |  Enabled  
Prohibit access to properties of components of a remote access connection  |  Enabled  
Prohibit access to the Remote Access Preferences item on the Advanced menu  |  Enabled  
Prohibit connecting and disconnecting a remote access connection  |  Enabled  
I changed these to the following:

Policy | Setting

Prohibit access to properties of a LAN connection   |  Disabled  
Prohibit access to properties of components of a remote access connection   |  Disabled  
Prohibit access to the Remote Access Preferences item on the Advanced menu   |  Disabled  
Prohibit connecting and disconnecting a remote access connection   |  Disabled

the domain admin can create a policy strictly for that user (put the user in his own OU i.e. wirelessenabled and then create a group policy that allows the connection for that OU.

As a one off you can go to Regedit and find Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Wireless\GPTWirelessPolicy and find the policy file location in the PATH sting.
(not sure if it is always a .tmp file in c:\windows\wlansvc\policies)

Then edit that file (as admin) and delete:
<denyAllIBSS>true</denyAllIBSS>
<denyAllESS>false</denyAllESS>

Then save, exit and reboot (not connected to your network).
Settings will be reset on the next network logon or when reconnecting to the network after a while through the policies.
