Hi all,
This is new to me so I hope i provide you with sufficient information.
We are experiencing problems on our NPS server on Win 2008 R2 Standard.
We use NPS to authenticate wireless clients that want to connect to the network by EAP-MSCHAP v2.
All day long we see log entries showing Event 6274: Network Policy Server discarded the request for a user.
When taking a closer look at a these entries, we see that there are a lot of authentication requests with empty usernames
ending up as "domain\Guest" originating only from Apple devices.
Has anyone had this problem before?
Below is an event entry in more detail:
