Client getting a Certificate error message

Hi,

 

I have a Microsoft NPS customer that is using a GoDaddy certificate.  The clients are connecting, however, before they connect, they are getting the following error popping up;

 

the server presented a valid certificate issued by Entrust.net Secure server certification Authority, but Entrust.net secure server certification authority is not configured as a valid trust anchor for this profile.  Further, the server is not configured as a valid NPS server to connect to for this profile

 

Can anyone tell me what this is happening and where I should be looking in order to fix this?

 

Thanks..

I also would like to add that it's not only happening on Window devices, by Android, Apple IOS etc.  Basically, it happend everything they first try to authenticate.  they acknowledge it, and get authenticated.  If they disconnect and then try to reconnect they are prompted again with this error.

Do you have the root CA certificate installed on the NPS server?

Re: Client getting a Certificate error message

If you open the server certificate inside the NPS PEAP settings, are there
any chain trust errors?
