We have an NPS RADIUS auth. problem. Currently we are running a site with 1 RODC and 1 RWDC in paralell as we are transfering all the services to the new RWDC and preparing to demote the RODC. What is left to transfer before i demote RODC is NPS. We were testing RADIUS yesterday evening by powering of the old RODC and switching RADIUS server IPs on the APs. I installed NPS on RWDC and ”copied” the settings to match RODC. Made a wireless policy and created the RADIUS client entries. Checked Shared secret on both AP and NPS. Added RWDC to RAS and IAS servers group, rebooted and requested RAS and IAS server certificate. Checked certificates. Trusted Root Certification Authorities match and Intermediate Certification Authorities match on both DC's. BUT... We can’t get the clients to auth. The clients Wifi NIC hangs on ”confirming identity” when RADIUS server is set to the RWDC in the AP the client is connecting to. RODC or our backup NPS in a remote site works. Must be something i’m missing... Ran wireshark on the client NIC as it was connecting.
