AAA not authenticating to Win Radius server

peperg — Sun, 10 Mar 2019 21:57:37 GMT

I have a client that is trying to use a Windows ISA server as a RADIUS server to authenticate PPTP connections to a 515e. I know that the VPN connection is working since I can set it up to use local auth and it works just fine. When I set up radius the clients get an error that says that it did not get a response from the server (I think it was 761).

The relevant config and the debug ppp negotiation and debug ppp error is below, I am looking to see if there is a way to test the RADIUS server other than having someone try to connect. Or if anyone has had any experience setting these up.

You get the details for troubleshooting the Cisco ACS server from the following URL: http://www.cisco.com/en/US/products/hw/vpndevc/ps2284/products_configuration_example09186a0080094a03.shtml

Windows ISA server not Cisco ACS. I have resolved the issue by rebuilding the ISA services on the Windows server.
