I'm having real problems trying to get ArcGIS 10.1 prerelease to authenticate users at the web tier.   I've tired virtually every combination of different settings and I cannot get the web tier authentication to work.

I've configured ArcGIS server 10.1 to use Windows domain for Users, ArcGIS builtin Account and to Authenticate at the web tier.
I've installed the IIS WebAdaptor and configured it with the same preshare key etc.
I've enabled Windows Authentication on the arcgis app in IIS, however the server is still challenging the user for credentials with a dialog box.  When I enter the credentials it returns a HTTP status code of 498.0

The only way I've had the web adaptor working if only when I authenticate at the GIS Server (and thats been via the different user stores ArcGIS user, LDAP & windows). 

Does anyone have any suggestions?

I'm using Windows Server 20008 R2 (IIS 7.5).  The app pool of the webadaptor is in integrated mode.
