To address this challenge, it is recommended that the computer certificate issued to the client be retrieved from the issuing CA and placed in the local computer’s Untrusted Certificates store on each VPN server, as shown here. Once again, revoking the computer certificate and publishing a new CRL is recommended, but isn’t immediately effective. Since device tunnel connections don’t use the NPS for authentication, blocking devices from establishing Always On VPN connections requires a different technique. Once complete, move the deny access policy so that it is before the policy that allows VPN access. Click Next four times and click Finish.Select the security group create for denied users.Select Remote Access Server (VPN-Dial up) from the Type of network access server drop-down list.Enter a descriptive name for the policy in the Policy name field.Right-click Network Policies and choose New.Once the security group has been created, open the NPS management console (nps.msc) and perform the following steps. In addition, a Network Policy must be created on the Network Policy Server (NPS) that denies access to users belong to this security group. To immediately prevent users from accessing the VPN, a security group must be created in Active Directory that contains users that will be denied access.
The process of flushing certificate revocation caches is challenging and time consuming as well. However, this will not instantly prevent VPN access because revocation information is cached on the VPN and NPS servers, as well as any online responders. When certificates are used for authentication, for example when a device tunnel is deployed, or a user tunnel is configured to use Extensible Authentication Protocol (EAP) with user certificate authentication, immediately revoking issued user and device certificates and publishing a new Certificate Revocation List (CRL) is recommended. However, additional steps may be required to disconnect current VPN sessions or prevent future remote connections. Typically, this means that user accounts and computer accounts in Active Directory are disabled, and any issued certificates are revoked. Commonly this occurs when an employee is terminated or leaves the company, or if a device is lost, stolen, or otherwise compromised.

Once Windows 10 Always On VPN has been deployed in production, it may be necessary at some point for administrators to deny access to individual users or computers.
