Microsoft Windows and Captive Portal issues?
Raise your hand if you're having issues with customers trying to connect through your captive portal and are getting "Diagnose Connection Problems" in IE even though ipautoconfigurationenabled = 0, and firefox and chrome connect just fine.
Also, any one having any issues with windows 8? Gee, I wonder…..
All wifi-hotspots have mostly Microsoft Windows system-based users**
You're actually stating that the Captive Portal doesn't work for you.
There is good news, and bad: you're wrong ;)
** The exception might be: Apple's main headquarters.
