no authorization extensions!

i have removed nps ( including isa.xml file) role, , reinstalled it, same issue.

thanks reading , assisting me.



hi,

this might certificate issue.

1. ensure root ca certificates installed correctly on nps server , wireless client computers:

2. ensure server certificate installed correctly on nps server.

another reason the ap configred use .4 addr.  nps responded .6 because primary addr.

resolution

added .4 addr nps properties default addr.

if not help, please provide more information. can check logs such iassam.log, iaslog.log client side event log.

hope helps.
