Issue while accessing report server With IE9

Hi,

We are getting problem while we access report server from IE9. When the user try to open the report server, it always prompts to enter the user ID and pwd.

Even though they change the Internet option settings (Local Intranet->Custom leve->User Authentication -> Automatic Logon to intranet zone) we are getting the error

Could anyone please help me with this in solving?

Thanks,

Bharadwaj.
