Radius with dynamic dns clients

[EricB]

I am using dynamic DNS on client firewalls to register them and in turn, I'm
loading them into RADIUS for centralized security with the hostname as the
address of the Radius/IAS client. If I attempt to login to the remote device
anytime after the IP changes, it fails as IAS does not seem to refresh its IP
entry for that hostname on any type of cycle. Wondering if anyone knows how
to fix this and/or force the IAS server to refresh it's hostname/ip cache?
Nothing obvious in the registry. Guess I could stop/start the service on a
scheduled basis but have not actually tried that to see if it works or if the
entry is still tied to the original IP...

Try restarting the service. Since you probably have redundant RADIUS
servers (everyone should), there's no problem restarting single service
at any time.
