Forms Configuration is suddenly asking for a user and password at a Windows Auth Prompt from IIS. I am unable to login with my domain account and have never been prompted to login even though Win Auth is enabled on the site. If I enable anonymous Auth then it says 401.0 - Unauthorized.
Where is it configured for which windows accounts have access, I have never needed to configure my windows account to have access in any previous installs.
Edit: I found that I can succesfully access the site from the WAN, just not on the server itself, never had this happen before. All forms servers are usually configured locally.
