We recently setup reporting services on a 2008 SQL box. Previously we had this installed on 2005. All reports are running fine but I continually get prompted for authentication when connecting to the report server. I know that anonymous access has been taken away in 2008 and it no longer uses IIS. However I am NOT an anonymous user anyway so I'm not sure why it can't get the credentials from my current session. Is there a configuration option that I might have missed?
