Previously I had IAS configured on a windows 2003 server and wireless worked great. I moved to my windows 20008 r2 server and just can't get it to work. I follow the microsoft documentation and setup NPS/certifcate services which are basically the same as was my 2003 setup. The only difference is I am running DHCP services from my firewall. I setup a windows 2008 dhcp server buty it would not give out IP's. Is it requred to configure a windows dhcp server or is it ok to run form the firewall? Anyway, here is the error I am getting when the test client will not authenicate: Event ID: 4402 Event ID: 18 an access-request message was received from Radius client 152.32.154. with a message Authenicator attribute that is not valid
