i am trying to get my Local machines IIS Server to validate me as a user in my mvc 3 site using the Razor Engine. i have my site and AppPools created and work properly if i have Anon auth enabled but the second i turn on windows authentication and disable anon authentication it keeps throwing a 401.2 error.

` can anyone tell me what i have to change\do to get it to work.

my host file has been updated with the following.

127.0.0.1 dev.local.mysite.com

and the site has been setup with the bindings pointing to dev.local.mysite.com

Just in case anyone has this problem the solution to my problem came in the form

under regedit go to

/HKLM\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0

add a REG_MULTI_SZ value called

BackConnectionHostNames 

and put the wanted URL into the Registry Entry
