I was fixing one of our associates intranet where single sign on is not working. Our intranet is set as homepage but for some reason it keeps asking for user credentials, though it loads the intranet login page instead. Then I decided to reset IE 9's all settings and delete personal settings. When I restarted the IE 9 it went worst that intranet wont even load at all and shows the below error.
"Your browser supplied NTLM authentication data.

is configured to use Integrated Windows Authentication."
Please help me... Thanks in advance.
