The RadiusNT services runs using the "radius" account. The DSN is "Radius",
using "sa" for the login. Should these be set differently?

I tried this out several times today after typing in "c:\radius" into the
RadiusNT Admin and restarting RadiusNT.
I tested the SNMP concurrency checking--sometimes it worked; sometimes it
caused RadiusNT to hang with the following error being displayed on the
Initialization of the dynamic link library c:\winnt\system32\user32.dll
failed. The process is terminating abnormally.

All subsequent authentications (by regular customers as well as me) failed
because of Radius timeout. I had to stop RadiusNT and remove the
"c:\radius" that I entered into the Admin before restarting
RadiusNT--otherwise, the same problem would have occurred again at some

Here's what the debug info reported (for the connections that caused
RadiusNT to hang):
