You didn't say what version of RadiusNT you are running. RadiusNT 3.0
has a local cache that could cause this scenario. There are options you
can tune to tell it how long to keep a user in the cache before removing
them or updating them. There is also another option to tell it how
often to check for changes to the user information.

Since the cache is volatile by default, restarting the service would
clear the cache.
