NPS Error Code 23 RRS feed

  • General discussion

  • I just newly setup NPS for 802.1x wireless authentication. When a user tries to connect to the wireless network it is not connecting. Checked the log and its showing an error with Error code 23. Any thoughts on why this would be happening? I have the RADIUS clients on the NPS server set for all the WAP's on the network. Computer has the certificate that is setup in NPS.
