Windows 7 / Windows 8 - Wireless error - Valid Trust Anchor

Hi All,

I would like to know how to get this issue fixed.

We are using Aruba 3200 in our network .

Wireless Error - Windows 7

 

It will work fine if I click on "Connect", but after few days again prompt.

 

Currently, We are doing manually workaround by configuring not to prompt

 

Workaround

 

Is this the recommanded way to eliminate the warning popup in an enterprise?

 

 

Your help much appriciated.

Is not a recommended way to just get rid of the warning is a recommended setting actually

look at my tread i create why you should check that box and also other things you should do...

Anyways even if you not check it there is something wrong in there.. it looks like if your computer were not saving that wireless profile.... i mean if its saved correctly it should not appear again... But well like i said it is a recommended setting, look at the link i pasted you up...

 

Cheers

Re: Windows 7 / Windows 8 - Wireless error - Valid Trust Anchor

If these Windows machines are joined to an Active Directory domain, you can create a GPO that configures the wireless profile.

 

Computer Configuration > Policies > Windows Settings > Security Settings > Wireless Network (802.11) policies.

 

Be sure you select the Root CA and enter in the names of the RADIUS servers (name that is presented in the cert).

 

 

If they are not AD machines, there is a free tool from Swansea University that can be customized to configure the client supplicant with the appropriate connection information. https://su1x.swan.ac.uk/

 

We use both methods on our campus.

Strangely enough, I have just come across an article that suggests that you need to also configure the "autoenrollment" policy along with pushing that certificate to the trusted CA store, otherwise your clients will not trust it:
