Hey all,

 

We have a few examples of Windows computers that refuse to connect to one of our Wi-Fi access points. Other computers (desktops and laptops) in our domain are able to connect to this access point with no issue.

I ran a PS script from the MS site: https://download.microsoft.com/download/B/D/8/BD821B1F-05F2-4A7E-AA03-DF6C4F687B07/dgreadiness_v3.6.zip, which I disabled the DeviceGuard (DG) and Virtual Based Security (VBS) on one laptop. This laptop was then able to connect to the access point with no issue. Subsequently, when running the same script (this time to enable DG and VBS), the laptop once again, was not able to connect to the access point! 

Now, we are trying to figure out why this only occurs on some computers and why when disabling DG and VBS, the computers are able to connect to the access point then when enabling DG and VBS, the same computers no longer can connect to the access point.

Any ideas about what is going on?

Thanks!
