Problem : A RADIUS message was received from the invalid RADIUS client IP address xxx.xxx.xxx.xxx
I have server 2008 installed and the Event ID 13 has a error message
A RADIUS message was received from the invalid RADIUS client IP address 192.168.0.210.
and it crashes the server
Solution : A RADIUS message was received from the invalid RADIUS client IP address xxx.xxx.xxx.xxx
One option to determine whether the crash is a result of the event, is to add the IP 192.168.0.210 as a client.
Is 192.168.0.210 a server or a workstation? Is it configured as a VPN endpoint and uses radius? Do you know the type of radius packet that is being sent access-request? acctounting packet?
get wireshark from wireshark.net or use the micorsoft network monitor to capture the packet to see what it is. Do you have a minidump c:\windows\ \Memory.dmp?
You would need to use the windows debugger with the windows 2008 symbols to analyze the dump file for the cause of the crash.
