So it seems that pass-thru authentication just seems not to live in happy co-existence with IIS. I can configure it, and it will work for minutes or even an hour. Then it just fails and won't authenticate. I can go, uncheck IWA and turn on anonymous, run the config wizard, and then turn anonymous off again/IWA on, run the wizard again and it starts to work.
What seems to trigger the break constantly is trying to hit NetFlow. NetFlow seems to break the whole thing. Any thoughts or suggestions?
