Windows 10 Credential Guard breaks WiFi

Recently, I ran into an issue with computers running windows 10 that would not connect to our WPA2-Enterprise encrypted wifi network.  When it failed to connect, there was no indication of why, only the message "Can't connect to this network."  The computers were able to connect to unencrypted networks and networks using a Pre-shared key for WPA encryption without issue. Checking the event logs on the RADIUS server to see why the comptuer failed to connect, there was no log entry for a connection attempt from the affected system.  The WLAN-Auto-Config log on the client listed a couple of errors, including Event ID 11006 and 12013, but other than showing that the failure reason was "Explicit EAP failure received", they didn't give much to go on: Log Name:      Microsoft-Windows-WLAN-AutoConfig/Operational Source:        Microsoft-Windows-WLAN-AutoConfig Date:          8/15/2016 1:11:20 PM Event ID:      11006 Task Category: MsmSecurity Level:         Err
