HI! I’ve got a Cisco PIX firewall 515E and use a Windows 2000 server’s Radius as an extra step of authorization for VPN users. At least twice a week, I get a call from an outside user that they cannot get into the VPN “authorization failed”. I have come to find that restarting the Windows 2000 server resolves the issue “every” time. There is never any errors in the logs, Radius is always running (though if I try to stop and start the service, I get an error that it cannot be stopped. I also use this server to dish out licenses to a number of our engineering packages so it’s a real problem to constantly restart the server and kick out all my engineers from their work. Any thoughts on this? How to repair a problem you can’t see? I’m close to just setting Radius up on another box and letting it go. Please help a frustrated admin 🙂
