Looking at the link you gave below it appears that NCSI is invoked for many 
reasons, but one is when a device connects to a new network, which is exactly 
what is happening here.  The clients change from the captive portal to the 
production network, but for some reason the balloon pops up as the network 
changes.  An nslookup from the production network to dns.msftncsi.com results 
in 131.107.255.255 as it is supposed to, so I'm not sure why this is happening.

I don't think that this happened when I was forcing the clients to register 
manually.  When that was in place they would see the progress bar, then get 
redirected successfully.

Cheers,
Andi

Oh yes, of course. Apologies I misread your email.

The balloon is very helpful in prompting the user to open the browser when the 
user enters the captive portal, but I am finding then that after they have 
configured their dot1x, and get auto-registered the balloon pops up again, 
right at the end of the registration process, which is the point that's 
confusing for the users.

Cheers,
Andi

Don't punch a hole through! You want users who are auto-registered not to see 
the bubble correct? Registered users don't see the portal so no need to punch 
through the portal.

It's actually very convenient that it opens this bubble if the user is behind 
the portal. It makes the user experience better on Windows Vista and up. And to 
be fair OS X Lion goes even a step further by opening a minimal safari browser 
if the proper WISPr attributes are present (which our portal support since a 
couple of versions back).
