When a wireless client is authenticated via 802.1x EAPOL. Is there any timeout on the windows client or will it stay authenticated until the network connection is lost?
Thanks

NPS event ID 6273 with reason code 7 specified domain does not exist Wireless connection
I am trying to troubleshoot NPS authentication issues for Wireless connectivity. When User is trying to connect , can't connect to this network, event ID 6273 with reason code 7 specified domain does not exist. NPS role is on PDC, registered in AD. User member of the domain(admin). I have tried the registry edit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\ControlProtocols\BuiltIn New entry DefaultDomain to force NPS to use FQDN instead of NETBIOS name as found in few threads. Not effective. NPS is still trying to Authenticate using NETBIOS Name. NPS is rejecting Access request from Access point. Tried uninstalling AV. Not effective. Tried using different type of authentication. Same error. Is this something related to Certificates installed on NPS. As far as I checked, subject name matches hostname, intended purpose is client and server authentication, not expired, root ca is present in certificate store. Is there anything else to be checked on certificate side. really stuck with this. Can't provide error message and details due to security reasons.

NPS - Radius authentication with user and password and MAC Filtering
Hi. I need some help with a NPS configuration based on Windows Server 2016 Datacenter.
In our infraestructure we need to autenticate users, through 2 steps together:
- 802.1X with user and password
- MAC Filtering into whitelist
We use Cisco WLC controller and domain controlers under windows server 2016
It´s possibly to do this?

NPS Authorization Only
Hello,
I have a VPN firewall (Cisco ASA) that is validating the client certificate and it also sends the CN, which is the username, to the NPS for authorization. That means that the NPS server can't authenticate the user, because it receives an empty password field in the RADIUS packet. Therefore, I want to skip the authentication and implement authorization only.
I can't find a way how to implement this. The NPS policy nevery matches, because the authentication already fails. Is there a way to skip the authentication on NPS?

Issue authentication wireless client using NPS
Hi
I have a working 802.1X wireless NPS setup but after upgrading one of the clients to Windows 10 1909 when trying to authenticate I get domain\Guest instead of the actual AD user in the event viewer. Obviously the client cannot authenticate. The user is logged in with his AD account. Other clients can authenticate on the same AP so the issue is related to that particular client. Any ideas?
Thank you

Connect with a non domain member computer to a 802.1x certificate protected network,
Hy Everybody!
I have set up a 802.1x network at my company, and i want to connect a few non domain joined computer to.
I have an nps server set up to join the computers with certificate.For the domain joined computers i have a gpo to enroll a certificate for this.
I have set up a cep/ces service to enroll a computer certificate, and i can enroll a copy of the default computer certificate, but no luck to connect to the wifi network.

Can someone give a little advise to make this work?

NPS Extension for Azure MFA: IP_WHITE_LIST_WARNING::IP Whitelist is being ignored as source IP is missing in RADIUS request in NasIpAddress attribute.
Hi,
After installing Azure MFA extension on our NPS server and registering with our tenant we started seeing Errors (event ID 4) from Microsoft-AzureMfa-AuthZ/AuthZAdminCh for the client IPs what were white listed in the registry per KB https://docs.microsoft.com/en-us/azure/active-directory/authentication/howto-mfa-nps-extension-advanced#ip-exceptions
It looks like one of our RADIUS clients (access point) is not sending ratNASIPAddress attribute in the request.
Is ratNASIPAddress something we need to configure in NPS or should be done on the client itself?
Thanks

Direct Access connection issue since replacing certificate
Hello all,
I have started a new role where the organisation used Direct Access. I haven't used this before and unfortunately, the SSL certificate expired.
I have purchased a new domain wildcard and try to import/bind. This has been very difficult for me as the server is running Core edition which i'm not familiar with. I can't tell you how many hours i've spent trying to fix this :-(
The certificate is installed and appears to be ok as if I browse to https://da.domain.org - it reaches the IIS landing page and the certificate shown is the new one but clients aren't able to connect.
Here is a screenshot of the errors in Remote Access Management Console. I think perhaps the certificate hasn't be bound correctly? One thing I did notice is that the new wildcard doesn't have a friendly name, would this matter?

export import from 2016 to 2012
Hi,
Is it possible to export for NPS server 2016 to NPS server 2012 R2 ?
When I follow either powershell or netsh it failes to import the xml file from 2016, so I guess there is no compatibility that way ?
If that is the case, Is there a command for me to import only the radius clients ?
Thanks for reply
/Regards Andreas

OCSP stapling with NPS
When implementing EAP-TLS, can NPS staple and OCSP response to its handshake so clients that don't have CRL (and, obviously, cannot download it at the EAP phase) can validate the NPS certificate?

802.1X Authentication Across Forest
I already have an NPS server which is used for wireless authentication using Computer Certificates.
I have acquired a second domain/forest, which is reachable to a point there is a two-way forest trust. I have even been able to effect cross-forest certificate enrollment.
Now the issue arises when I try connecting domain 2 machines, which have valid certificates, to the EAP wireless network:
Logging Results:Accounting information was written to the local log file.
Reason Code:
16
Reason:
Authentication failed due to a user credentials mismatch. Either the user name provided does not map to an existing user account or the password was incorrect.
So I am thinking a need to find a way to forward these requests to the second domain. Could you point me in the right direction on how to achieve this?

RADIUS packets seeming to be ignored on Server 2016 with Network Policy Server installed and configured for Radius
Just as whats on the tin: Radius packets seeming to be ignored on Server 2016 with Network Policy Server installed and configured for RADIUS. I have a AP setup to use RADIUS to authenticate clients and a Server 2016 setup as a DC with network policy server configured with a policy for Radius wireless clients, In Wireshark the initial access request packet it sent several times with a delay in between each, and with the server not responding. In the Security event log there is nothing involving network policy server and appears to be a firewall issue however the firewall has the allow rules for RADIUS in it.
Feel no hesitation to ask be to send specific screenshots for more info, I thank you for your answer in advanced.

NPS: Override User-Name and User Identity Attribute
After configuring NPS and using http://technet.microsoft.com/en-us/library/dd197535%28WS.10%29.aspx it's possible to authenticate based on MAC Addresses.
Is it by design that all authentication requests handled, are changed to MAC Address Authentication?
We want to have three Network Access Policies, two based on Active Directory Account, one based on MAC Address.
After entering the registry values and rebooting the server, it's only possible to authenticate based on MAC Address.
Do we need seperate NPS servers, one for MAC based authentication and one for A.D. account authentication?
Thank you in advance.

Allowing access to users with bad credentials
I'm trying to set up a MAC-based-RADIUS-auth/public network, i.e; if the device's MAC address is on AD allow it and set its VLAN to the proper network, if its not, leave it there but allow it access nevertheless. From there a captive portal would allow access
to guests and [forms-]authenticate users if needed. Since portals can read from AD, it can get the MAC addresses to which it should not present itself. It seemed all very straightforward.
I figured the Allow clients to connect without negotiating an authentication method constraint would be enough until it was time to see the logs to build the policy that I realized thatwithout⍯ with failed [authentication method].
So even though both situations result in an unauthenticated user, they're very different. :/
How, if possible, can I allow clients to connect when they input the wrong credentials--this is basically a given because the APs automatically convert MAC addresses to usernames.
Thanks!
